Description
Technical Field
The utility model belongs to the technical field of chemical reaction device, in particular to downward injection formula reactor that can be used to nitric acid oxidation sec-octanol preparation n hexanoic acid.
Background
The reaction formula for preparing the n-hexanoic acid by oxidizing the sec-octanol with the nitric acid is as follows:
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a downward injection formula reactor utilizes this reactor to prepare n hexanoic acid with the sec octanol of nitric acid oxidation, and the reaction is complete, can effectively avoid polluting.
In order to achieve the purpose, the utility model adopts the following technical scheme: a downward injection type reactor comprises a reaction kettle with a feeding port and a discharging port, wherein the middle of the upper part of the reaction kettle is connected with a liquid outlet of a liquid injection vacuum pump, a liquid outlet pipe of the liquid injection vacuum pump extends into the bottom of the reaction kettle, a liquid inlet of the liquid injection vacuum pump is connected with the lower end of the reaction kettle through a connecting pipe which is connected with a non-leakage pump in series, and a suction port of the liquid injection vacuum pump is communicated with a reaction liquid inlet pipe, the side surface of the upper part of the.
A heat exchanger is arranged on a pipeline between the liquid inlet of the liquid jet vacuum pump and the non-leakage pump, and a liquid pipeline penetrates through the middle of the heat exchanger.
The suction port of the liquid jet vacuum pump is communicated with the reaction liquid inlet pipe through the transverse pipe of the three-way pipe, and is communicated with the side surface of the upper part of the reaction kettle through the vertical pipe of the three-way pipe, and the vertical pipe is provided with an air inlet switch.
The upper part of the reaction kettle is provided with a waste gas outlet.
The utility model discloses when using, in adding reation kettle to second octanol and catalyst in advance, open the no leakage pump and inhale nitric acid and air through liquid jet vacuum pump suction mouth, still inhale the nitrogen oxide class gas that emits in the reaction simultaneously. The oxidation of low-valent NO into high-valent NO by the oxidation of airxCan directly participate in the reaction, thereby effectively reducing the NO content in the tail gas, reducing the workload of tail gas treatment (only by using dilute alkaline water with the pH of less than 9), and lightening the air pollution. Nitric acid, air, secondary octanol, catalyst, nitrogen oxide gas and the like are uniformly mixed in the jet pump, and jetted liquid is sent to the bottom of the reactor through the liquid inlet pipe, so that the liquid phase is fully stirred, the reaction is facilitated, and the reaction is complete. The whole reactor forms a complete circulation loop, no dynamicsealing part exists in the circulation system, no abrasion exists, and leakage is effectively treated.
