Novel special reaction kettle for esterification reaction

Abstract

The invention discloses a novel special reaction kettle for an esterification reaction and relates to chemical equipment. The reaction kettle comprises a reaction kettle main body, wherein a feed inlet is formed at the upper end of the reaction kettle main body and a discharge opening is formed at the lower end of the reaction kettle main body; a gas outlet is formed on the side wall of the reaction kettle main body; the reaction kettle further comprises a controller; a heat exchanger and a temperature sensor are arranged in the reaction kettle main body; a vacuum pressure gauge is arranged at the top of the reaction kettle main body; the vacuum pressure gauge, the heat exchanger and the temperature sensor are electrically connected with the controller, respectively; a ceramic layer is arranged on the surface of the inner wall of the reaction kettle main body; and a jacket is arranged on the outer surface of the side wall of the reaction kettle main body. The reaction kettle disclosed by the invention is simple in structure, novel in design, safe and reliable to operate and good in product quality, the reaction time is greatly shortened, and the reaction kettle has very high practicality.

Description

technical field [0001] The invention relates to a chemical equipment, in particular to a novel special reaction kettle for esterification reaction. Background technique [0002] At present, in the chemical synthesis reaction, the process of esterification reaction is difficult to control accurately, especially in a certain stage in the middle of a series of reactions, and it is even more difficult to grasp. Continued reaction may cause a large number of side reactions, and even cause the product to be scrapped. This intermediate stage is difficult to detect because the apparent parameters of the reaction, such as temperature, pressure, flow, etc., do not change significantly. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a new special reaction kettle for esterification reaction, which has simple structure, novel design, safe and reliable operation, good quality of finished products, great...
