Description

Continuous preparation system and preparation method of triisobutyl aluminum
Technical Field
The invention belongs to the technical field of triisobutyl aluminum production, and particularly relates to a triisobutyl aluminum continuous preparation system and a preparation method.
Background
The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.
Triisobutyl aluminum is a main catalyst for producing synthetic rubber, synthetic fiber and synthetic plastic, and is generally synthesized by using active aluminum powder, isobutene and hydrogen at high temperature and high pressure. In the production process of triisobutyl aluminum, a preparation system directly determines the conversion rate of raw materials, the quality of products and the energy consumption.
In an original production system, a reaction kettle is used for batch feeding, and the product quality fluctuation is large and the energy consumption is high due to frequent temperature rise and fall through the steps of temperature rise and pressure rise, constant-temperature reaction, temperature reduction and discharging and the like.
When the yield needs to be increased, the volume of the reaction kettle generally needs to be increased, and as the reaction is carried out at high temperature and high pressure, the larger potential safety hazard is easy to exist when the volume of the reaction kettle is increased.
In addition, since the reaction raw materials of triisobutylaluminum are active aluminum powder, solvent, isobutylene and hydrogen, three phases of solid phase, liquid phase and gas phase coexist in the reaction system, and the presence of bubbles easily reduces the contact area of the raw materials, thereby affecting the normal progress of the reaction. Especially, when the volume of the reaction kettle is large, the reaction kettle is difficult to be fully stirred, and three-phase raw materials are difficult to be fully mixed, so that the reaction rate is low, the reaction conversion rate is low, the reaction needs to be carried out for a long time under high temperature and high pressure, and great potential safety hazards exist.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a continuous preparation system and a continuous preparation method for triisobutyl aluminum.
In order to achieve the purpose, the invention is realized by the following technical scheme:
in a first aspect, the invention provides a continuous preparation system of triisobutyl aluminum, which comprises a plurality of reactors connected in series, wherein a stirrer is arranged in each reactor;
the stirrer comprises a rotating shaft, a first propeller blade, a centrifugal propeller blade and a second propeller blade, wherein the first propeller blade, the centrifugal propeller blade and the second propeller blade are sequentially arranged on the rotating shaft, and the rotating directions of the first propeller blade and the second propeller blade are opposite;
the centrifugal paddle comprises a disc body and a plurality of arc-shaped blades arranged on the side face of the disc body, and the arc-shaped blades are arranged in an annular mode relative to the axis of the disc body.
In a second aspect, the invention provides a continuous preparation method of triisobutyl aluminum, which comprises the following steps:
the active aluminum powder, the solvent and the isobutene are mixed preliminarily in proportion and then are injected into a reactor at an initial position in proportion with hydrogen;
the motor is started to drive the rotating shaft to rotate, and simultaneously drive the first propeller blade and the second propeller blade to rotate in different directions to drive the three-phase reaction raw materials to flow back and forth in the reactor; meanwhile, the centrifugal blades in the middle of the rotating shaft throw the three-phase reaction raw materials in the middle of the reactor to the inner wall of the reactor;
two materials flowing back to back flow meet the inner wall of the reactor, flow reversely to two sides and impact with material fluid thrown out by the centrifugal blades;
the gas is fully dispersed in the reaction system and bubbles in the reaction system are eliminated.
The beneficial effects achieved by one or more of the embodiments of the invention are as follows:
the preparation system of triisobutylaluminum can realize higher reaction rate and reaction yield by connecting a plurality of reactors in series and maintaining the temperature required by the reaction by utilizing the heat released by the addition reaction through multi-stage reaction. Because the volume of each reaction unit is small, the materials in each reaction unit can be fully mixed, and the potential safety hazard can be effectively reduced.
Because the reaction system of the triisobutyl aluminum coexists in three phases of gas, liquid and solid, the traditional microchannel reactor (with the diameter of micron order) is adopted, so the blockage of the microchannel reactor is easily caused, and the uniform mixing of the three-phase reaction raw materials is not easily ensured. Therefore, the reactor provided by the invention is provided with a plurality of reaction units and the stirring device in each reactor, so that the blockage of the reactor can be effectively prevented, and the full mixing of the three-phase reaction raw materials is facilitated.
The more key structure is the agitator in every reactor, and the propeller blade of (mixing) shaft both sides revolves to the opposite, when the rotation axis was rotatory, can drive both sides propeller blade revolve to the opposite to it flows rapidly (i.e. flows towards the top and the bottom of reactor respectively) when two strands of fluids in the drive reactor touch the reactor inner wall to drive the material in the reactor after both sides flow rapidly, and the rapid reverse is and the diffusion flow all around of orientation, and the velocity of flow is higher.
And the centrifugal blades in the middle of the rotating shaft can quickly throw the materials in the middle of the reactor to the inner wall of the reactor. At the moment, three high-speed fluids are collected in the middle area of the reactor, the flow direction of the centrifugally thrown fluids is vertical to that of the refluxed fluids, so that a large impact and shearing effect is generated, bubbles in three-phase materials can be eliminated as much as possible, and simultaneously, the raw materials are well mixed, so that the contact area among the raw materials is increased, and the reaction rate and the reaction conversion rate are increased.
In addition, the propeller blades on the two sides of the stirring shaft have opposite rotating directions, and the driven fluid flows to the top and the bottom of the reactor respectively, so that the stability of the reactor is improved.

Detailed Description
It is to be understood that the following detailed description is exemplary and is intended to provide further explanation of the invention as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
In a first aspect, the invention provides a continuous preparation system of triisobutyl aluminum, which comprises a plurality of reactors connected in series, wherein a stirrer is arranged in each reactor;
the stirrer comprises a rotating shaft, a first propeller blade, a centrifugal propeller blade and a second propeller blade, wherein the first propeller blade, the centrifugal propeller blade and the second propeller blade are sequentially arranged on the rotating shaft, and the rotating directions of the first propeller blade and the second propeller blade are opposite;
the centrifugal paddle comprises a disc body and a plurality of arc-shaped blades arranged on the side face of the disc body, and the arc-shaped blades are arranged in an annular mode relative to the axis of the disc body.
In some embodiments, multiple reactors arranged coaxially in a vertical direction share the same axis of rotation.
In some embodiments, the reactor has an internal diameter of 10 to 100cm, preferably 20 to 80cm, more preferably 20 to 60cm, even more preferably 20 to 40cm, and preferably 20 to 30 cm.
In some embodiments, the height of the reactor is 10 to 100cm, preferably 20 to 80cm, more preferably 20 to 60cm, even more preferably 20 to 40cm, and preferably 20 to 30 cm.
In some embodiments, the number of reactors is 2 to 200, preferably 2 to 150, more preferably 3 to 100, and even more preferably 10 to 50.
The number of reactors is not limited herein, as the number of reactors can be adjusted according to the process conditions and the volume of the reactor, and so on, as long as the series connection of a plurality of small reactors falls within the protection scope of the present invention.
In some embodiments, the ratio of the length of the first and second propeller blades to the rotational axis is 1: 3-6. This length ratio may define the mounting position of the two propeller blades on the rotation axis and the length occupied on the rotation axis. When the length of the propeller blade is short, the propeller blade is far away from the top or the bottom of the reactor, and the high-speed fluid driven by the propeller blade is high in resistance by other fluids in the process of flowing to the inner wall of the reactor, so that the flow speed of the fluid when the fluid impacts the inner wall of the reactor is influenced, the flow speed of the three fluids when the three fluids are collected is further influenced, the stirring and shearing effects are further influenced, and the elimination effect on bubbles is weakened.
Preferably, the ratio of the diameter of the first and second propeller blades to the diameter of the reactor is 1: 1.5-4, preferably 1: 2-3. When the diameter of the propeller blade is too small, the flow of the fluid driven by the rotation of the propeller blade is small, when the material with small flow impacts the inner wall of the reactor and is baffled and then dispersed in a space with large volume, the flow velocity of the fluid is low, and the mixing and shearing acting force generated when three fluids converge is weak. When the diameter of the propeller blade is too large, the resistance generated in the stirring process is large, and the energy consumption is easily increased.
Preferably, the ratio of the diameter of the centrifugal blades to the diameter of the reactor is 1: 2-4, and the diameter of the centrifugal blade is smaller than that of the propeller blade.
The fluid that the rotatory in-process of centrifugal paddle was thrown away is perpendicular to two strands of fluids that the baffling returned, and then produces the shearing force, and when setting up more than adopting, the fluid that throws away can overcome fluid resistance, shears the fluid that the baffling returned, and then can produce good shearing mixing effect.
When the diameter of centrifugal paddle is greater than the diameter of propeller blade, two strands of fluids that the baffling returned can strike centrifugal paddle, and centrifugal paddle can play the effect of blockking to the fluid that the refluence returned simultaneously, influence the mixing effect between the material.
In some embodiments, both ends of the rotating shaft are mounted on the reactor. To improve operational stability.

In a second aspect, the invention provides a continuous preparation method of triisobutyl aluminum, which comprises the following steps:
the active aluminum powder, the solvent and the isobutene are mixed preliminarily in proportion and then are injected into a reactor at an initial position in proportion with hydrogen;
the motor is started to drive the rotating shaft to rotate, and simultaneously drive the first propeller blade and the second propeller blade to rotate in different directions to drive the three-phase reaction raw materials to flow back and forth in the reactor; meanwhile, the centrifugal blades in the middle of the rotating shaft throw the three-phase reaction raw materials in the middle of the reactor to the inner wall of the reactor;
two materials flowing back to back flow meet the inner wall of the reactor, flow reversely to two sides and impact with material fluid thrown out by the centrifugal blades;
the gas is fully dispersed in the reaction system and bubbles in the reaction system are eliminated.
The invention is further illustrated by the following figures and examples.

The end of the rotating shaft 3 is connected to the motor 2, and since the volume of each reactor 1 is small, it is relatively easy to share the same rotating shaft among a plurality of coaxially arranged reactors 1.
The inner diameter of the reactor 1 was 30cm and the height of the reactor 1 was 30 cm. The number of the reactors 1 is 50. The length ratio of the first propeller blade 4 and the second propeller blade 6 to the rotary shaft 3 is 1: 4.
The ratio of the diameter of the first propeller blades 4 and the second propeller blades 6 to the diameter of the reactor 1 is 1: 2. the ratio of the diameter of the centrifugal blades 5 to the diameter of the reactor 1 is 1:3 and the diameter of the centrifugal blade 5 is smaller than the diameter of the propeller blade.
