Esterification reaction kettle for butyl acetate production

Abstract

The invention discloses an esterification reaction kettle for butyl acetate production, and belongs to the technical field of butyl acetate production equipment. The esterification reaction kettle comprises a fixing base and a fixing frame, a circular reaction device is arranged on the fixing frame and comprises a body, connecting mechanisms are arranged at the two ends of the body, and a driving mechanism is arranged on the fixing frame; two ends of the main body are respectively provided with a magnetic stirring mechanism and a dewatering mechanism, and a heating mechanism is arranged outside the main body. Compared with the prior art, the device has the beneficial effects that the device is simple in structure and convenient to use, the position of the main body is adjusted through the driving mechanism, the main body is heated through the heating device, a reaction solution is stirred through the magnetic stirring device, and gas transferred into the reaction chamber on the upper side is dewatered through the dewatering mechanism; the reaction rate of the esterification reaction can be effectively improved, and meanwhile, continuous proceeding of the esterification reaction in the reaction kettle is guaranteed.

Description

technical field [0001] The invention relates to the technical field of butyl acetate production equipment, in particular to an esterification reaction kettle for butyl acetate production. Background technique [0002] Butyl acetate is an excellent organic solvent, widely used in coatings, spices, leather, pharmaceuticals and other industries. [0003] The existing esterification reaction for butyl acetate production is generally catalyzed by concentrated sulfuric acid, and the esterification reaction is generally a reversible reaction. The traditional esterification technology uses acid and alcohol to heat and reflux under the catalysis of acid (usually concentrated sulfuric acid). Reaction, the main function of concentrated sulfuric acid is catalyst and water-absorbing agent, it can protonate the carboxyl group of carboxylic acid, enhance the electrophilicity of carboxyl carbon, speed up the reaction rate, and also remove the by-product water of the reaction to increase the...

AI Technical Summary

Problems solved by technology

[0004] When the existing butyl acetate is catalyzed by concentrated sulfuric acid, the concentration of concentrated sulfuric acid will be diluted due to the effect of product water, resulting in a decrease in the catalytic effect of the concentrated sulfuric acid, which in turn leads to a reduction in the rate of the esterification reaction and affects the production efficiency of butyl acetate.
