The tank body is a container piece of the carbonylation synthetized benzene acetic acid agitated reacting kettle, and stirring and reaction are both carried out in the tank body. The clamping sleeve is arranged outside the tank body and can be used for leading into cold water for cooling down reacting substances in the tank body. An upper end cover of a kettle barrel body is provided with the gas inlet which is used for connecting with a gas supply pipeline of carbon monoxide gas. The middle position on the uppermost end of the kettle barrel body is provided with the mechanical seal and the stirring motor is arranged above the mechanical seal. The stirring shaft is arranged below the mechanical seal and the stirring shaft is a hollow seamless pipe, both ends of which are sealed. The upper part of the stirring shaft is drilled with the gas inlet and the stirring paddle on the lower part of the stirring shaft is drilled with a gas outlet. The reaction time of the utility model is 3.5 hours and the absorption capacity of the carbon monoxide gas is 52.5NM< 3 >.
Description
The utility model relates to chemical reaction equipment, relates in particular to the carboxylation to synthesize phenylacetic acid reactor that a kind of suitable carbon monoxide (gas) and benzyl chloride (liquid) carry out gas liquid reaction.
Benzyl chloride and carbon monoxide carry out the process of oxonation synthesize phenylacetic acid, are the heterogeneous reaction processes that the reaction of a GAS ABSORPTION and liquid-phase catalysis is carried out simultaneously.Under the catalyst activity normal condition, catalyst reaction speed is very fast, the speed of whole process is controlled by the infiltration rate of CO, and the mass tranfer coefficient of CO in liquid phase is very little, this just requires CO gas to be dispersed in quickly and evenly in the liquid phase, carry out sufficient gas-liquid contact, improve the absorption probability of gas, and then improve the reaction rate of carboxylation to synthesize phenylacetic acid.Common stirred autoclave can not satisfy above-mentioned requirements far away.
The purpose of this utility model is, overcome the deficiencies in the prior art part, provide a kind of CO gas that can make to be distributed in effectively in the liquid phase medium, absorption is strengthened in circulation in carrying out repeatedly, liquid phase substance is mixed, the carboxylation to synthesize phenylacetic acid reactor that reaction rate can improve greatly.
A kind of carboxylation to synthesize phenylacetic acid reactor described in the utility model includes stirring motor, mechanical seal, air inlet, tank body, shaft, chuck, paddle and discharging opening and forms.Carboxylation to synthesize phenylacetic acid reactor described in the utility model, kettle barrel draw ratio are greater than 1, and the citation form of kettle barrel and the reactor of prior art are basic identical, and said tank body is a container piece of the present utility model, and stirring and reaction are all carried out in tank body.The outside of tank body is provided with chuck, can be used for feeding the usefulness that cold water is the reactive material cooling in the tank body.For guaranteeing the normal circulation of cooling water, be provided with water inlet pipe and the outlet pipe that feeds between tank body and the chuck in the outside of chuck.On the upper end cover of kettle barrel, be provided with air inlet, be used for linking with the steam line of CO gas.Centre position, the top at kettle barrel is provided with mechanical seal, and stirring motor is set above the mechanical seal, shaft is set below the mechanical seal.Shaft is sealed at both ends hollow seamless pipe, and shaft top is drilled with air admission hole, and paddle position, bottom is drilled with venthole, and in use, liquid level is between air admission hole and venthole.When shaft rotated at a high speed, the stirrer paddle place produced negative pressure, and the not absorbent CO gas of still ullage space is entered by the top pore, by the shaft mesopore, was come out by the venthole of bottom.The shear-mixed peptizaiton of utilizing paddle to produce redistributes gas in the liquid phase, and gas-liquid is fully contacted, and absorbs repeatedly, thereby makes oxonation liquid reach maximum absorption rate and GAS ABSORPTION amount.The center bottom of tank body is provided with discharging opening, is used to react the discharging of qualified material.
Use carboxylation to synthesize phenylacetic acid reactor technology described in the utility model, can make oxonation liquid reach maximum absorption rate and GAS ABSORPTION amount, compare with the common response still of prior art, reaction rate improves 30 percent, and the CO gas uptake improves 5 percent.With 2 cubic metres of reactors is example, drops under the identical situation of catalytic amount, and the reaction time of common response still is 5 hours, carbon monoxide uptake 50NM
3, the reaction time of carboxylation to synthesize phenylacetic acid reactor described in the utility model is 3.5 hours, CO gas uptake 52.5NM
