Description
Technical field
The present invention relates to ethynylation in a kind of production equipment of methyl butynol, especially a kind of methyl butynol production process
Reaction unit used by step.
Background technology
Methyl butynol, CAS 115-19-5, molecular formula：C5H8O.It is mainly used as synthesis medicine and agricultural chemicals, terpenes is fragrant
Material intermediate, acid inhibition inhibitor, viscosity stabiliser, viscosity reductant, nickel plating or copper-plated glazing agent etc..Also act as silicon rubber
The polymerization inhibitor of middle platinum catalysis hydrosilylation.In addition it is also serving as being used as solvent, the stabilization of chlorinated solvents.
The method of industrial synthesizing methyl butynol mainly includes ethynylation and separates two steps.
Ethynylation step is that, with acetylene, acetone as raw material, solid (mostly powdered) potassium hydroxide is catalyst, or liquid hydrogen
Sodium oxide molybdena makees catalyst, and ethynylation occurs in ethynylation device so as to ethynylation mixture is obtained.Its reaction equation is such as
Under：
HC ≡ CH+NaOH=HC ≡ CHNaOH
The complex compound of generation and water decomposition, generate methyl butynol：
Separating step is then that separating-purifying goes out methyl butynol from ethynylation mixture, generally main to include flash distillation, saltout
The steps such as dehydration, rectifying.
Fig. 1 illustrates the typical structure of ethynylation system, mainly mixed including stirred autoclave, auxiliary reactor and termination
Clutch.In ethynylation step, the ethynylation of acetylene and acetone is generally carried out in stirred autoclave, in stirred autoclave,
Alkynes, alcohol/ketone mixtures to lower and upper flowing, catalyst flow from top to bottom, mixed in the axial direction by density contrast, radially then lead
The stirring action of agitator is leaned on to mix, because the temperature difference of reaction system, concentration difference are larger, therefore the methyl fourth in stirred autoclave
The yield of alkynol is only capable of reaching 60% or so.To improve the yield of methyl butynol, conventional way is in stirring reaction at present
One auxiliary reactor is set again after kettle, material is carried out primary first-order equation again in auxiliary reactor, so as to improve methyl butynol
Yield.
Conventional auxiliary reactor structure is the reaction vessels such as the reactor with agitating device, reaction tower, reaction tube, its typical case
Structure is as shown in fig. 1.In auxiliary reactor, unreacted material carries out hybrid reaction again in the presence of agitator, from
And improve the yield of methyl butynol.Finally, the reaction stream in auxiliary reactor is passed through termination blender with reaction terminating agent
Interior mixing and terminating reaction, obtain ethynylation mixture.After further being reacted by auxiliary reactor, the yield of methyl butynol is reachable
To 85% or so.
The content of the invention
Further to improve the yield of methyl butynol, the invention provides a kind of anti-for producing the pair of methyl butynol
Answer device.
The technical solution adopted in the present invention is：Auxiliary reactor for producing methyl butynol, including auxiliary reactor master
Body, is communicated in the overflow pipe of auxiliary reactor lower body part, is communicated in the discharge nozzle of auxiliary reactor body top；It is characterized in that：
Auxiliary reactor lower body part is provided with hole plate, and the overflow pipe is communicated on the wall below hole plate.
Can excessively cause side reaction generation dimethylhexyne glycol due to local acetone, it is as follows：
So the material in must assure that auxiliary reactor is sufficiently mixed uniformly, therefore the setting of agitator is considered as necessary
's.
By taking the ethynylation system of the methyl butynol shown in Fig. 1 as an example, it has been recognised by the inventors that limitation methyl butynol yield
The problem of raising is essentially consisted in, in existing reaction system, material after initial reaction in stirred autoclave, by overflow pipe
Into auxiliary reactor bottom, hybrid reaction is being carried out again under the immixture of agitator.As material is constantly from overflow pipe
Flow into, material is gradually advanced from reactor lower part toward top in auxiliary reactor, and material constantly completes reaction during traveling, most
Enter from upper outlet pipe eventually and terminate blender.In the process, because the stirring of agitator causes liquid acutely to disturb so that
The product that auxiliary reactor top has carried out relatively fully reaction mixes with the unreacted material that bottom is newly entered from overflow pipe, makes product
Thing is mixed into unreacted material, reduces the reaction rate of unreacted material.Also cause to have just enter into the unreacted of auxiliary reactor simultaneously
Material quickly flow to auxiliary reactor top because of the violent flow-disturbing that stirring is formed, and the reaction that is not able to do in time also is just flowed into eventually from discharging opening
Only blender.
On the other hand, in flinging auxiliary reactor from auxiliary reactor bottom into the material of auxiliary reactor from overflow pipe, shape
Into the uneven fluid of flow velocity form bias current and dead angle in the reactor, it is impossible to ensure that all materials have in reactor and fill
The reaction time of foot and faster reaction rate, while also increasing the degree of side reaction generation.
To solve the problems, such as the above, inventor cancels the agitator in auxiliary reactor, is replaced with hole plate so that from overflowing
Flow tube flow into auxiliary reactor material by auxiliary reactor bottom hole plate stop, the fast fluid of flow velocity to both sides horizontal proliferation,
And be formed down vortex and disturb, play the effect for being well mixed material.Then bottom material is past by the hole of hole plate
Upper traveling, hole serves the effect for being uniformly distributed fluid, it is to avoid bias current and dead angle produce.Hole plate upper flow is upward simultaneously
The unreacted material just entered from overflow pipe with hole plate bottom during propulsion is in opposing spaced apart state, and (fluid is acutely disturbed
It is dynamic to be concentrated in hole plate bottom, it is ensured that hole plate upper flow is uniformly up advanced all the time, without flowing back to
Hole plate bottom), the fluid that can be prevented effectively from the relatively fully reaction of auxiliary reactor top mixes with unreacted material, or newly
Enter unreacted material and quickly flow to auxiliary reactor top.So as to ensure that all materials have the reaction of abundance in auxiliary reactor
Time and quick reaction rate, and then realize improving the purpose of methyl butynol yield.
As a further improvement on the present invention, the overflow pipe is communicated in auxiliary reactor bottom part body, of the invention
Mentality of designing, as long as being capable of achieving the purpose of the present invention on the side reaction wall that overflow pipe is communicated in below hole plate.But it is
The material of hole plate bottom is set to mix evenly, and hole plate top material forms fluid evenly, preferably by overflow
Pipe is communicated in auxiliary reactor bottom part body, and this also complies with the custom connected mode in industry.
As a further improvement on the present invention, the hole on the hole plate is can make the fluid by hole plate in hole
Gap plate top produces the mode of disturbance to set.Hole on hole plate can with it is any be conducive to fluid to evenly distribute in the form of set
Put, it is most typical such as equally distributed circular aperture, or other shapes aperture, and the or thin seam that uniformly or non-uniformly sets
Etc. diversified forms.But in order that obtain still can be continuous during hole plate top is advanced after lower flow passes through hole plate
There is the disturbance and mixing of appropriateness, further reduce local acetone excessively there is side reaction or form dead angle and bias current can
Can, can be by the hole on hole plate can make to be set by way of hole plate top produces disturbance the fluid of hole plate
Put.For example hole can be set to the inclined circular aperture that arranges according to certain rules, or likeness in form turbine blade shape
Gap etc..So that fluid during through hole plate under the water conservancy diversion of hole hole plate top formed appropriate vortex or
Disturbance, promotes hole plate upper flow further to mix.
As a further improvement on the present invention, the hole plate setting height(from bottom) be apart from auxiliary reactor bottom part body 15~
40cm.The setting height(from bottom) of hole plate is too high or too low all to cause hole plate bottom material to be difficult to form stronger disturbance (for example
Hole plate be installed on close to auxiliary reactor main body medium position even upper position when will be unable to realize the purpose of the present invention),
Mixed effect is poor.Inventor draws through overtesting, it is generally the case that hole plate installation site and auxiliary reactor bottom part body
Effect is preferable when distance is for 15~40cm.Additionally, the specific installation site of hole plate also with auxiliary reactor specification, overflow pipe material
The factors such as flow velocity, flow are relevant.Therefore the number range is only preferred values under normal circumstances, and concrete numerical value scope can be according to reality
Border situation is adjusted.
Additionally, due to general auxiliary reactor lower body part end socket welding position and auxiliary reactor bottom distance be about 20~
30cm, therefore can be directly by hole plate weld in end socket weld, in order to the installation and plant maintenance of hole plate.
The beneficial effects of the invention are as follows：1) agitator is substituted with hole plate, makes material to meet acetylene, acetone reaction rule
Form with methyl butynol productive prospecting is mixed, it is ensured that have the reaction of abundance into all materials in auxiliary reactor
Time and faster reaction rate, methyl butynol yield reaches 95% or so in can making ethynylation mixture.2) device structure letter
It is single, beneficial to industrially promoting.
