Abstract

The invention discloses an esterification apparatus, comprising an esterification kettle and a vacuum feeding device, wherein the esterification kettle comprises a kettle body and a kettle cover assembly, the kettle body is an integrally molded structure, is provided with a feed inlet I and a feed inlet II and is close to the kettle cover assembly, the feed inlet I and the feed inlet II are symmetric along the axis of the kettle body, the feed inlet II is provided with an ultrasonic nebulizer, the feed inlet I is connected with the vacuum feeding device, the vacuum feeding device comprises a gas phase / liquid phase converter and a liquid phase distributing and backflow device, the feed inlet I is successively connected with the gas phase / liquid phase converter and the liquid phase distributing and backflow device, the gas phase / liquid phase converter is connected with a vacuum-pumping device, a stirring device is fixedly mounted on the kettle body and comprises a motor and stirring blades, the stirring blades are connected with the motor, the motor is arranged on the upper end of the kettle cover assembly, and the stirring blades penetrates the kettle cover assembly into the kettle body and is located at the bottom of the kettle body. The esterification apparatus is scientific and reasonable in structure and convenient in feeding, realizes uniform stirring and is applicable to industrial mass production.

Description

technical field [0001] The invention relates to the technical field of alcoholization reaction equipment for plasticizers, in particular to an esterification device. Background technique [0002] In recent years, at present, many raw materials in the chemical industry are processed and then transformed into usable raw materials. Special equipment is used for processing raw materials, such as ester water. The so-called ester water includes ester powder and alkaline water. These two raw materials Mixed in a certain proportion. Esterification reaction is a kind of organic chemical reaction. It is the reaction of alcohol with carboxylic acid or oxygen-containing inorganic acid to generate ester and water. There are two types of responses. The esterification reaction of carboxylic acid with alcohol is reversible, and generally the reaction is very slow, so concentrated sulfuric acid is often used as a catalyst. Polycarboxylic acid reacts with alcohol to generate various esters...
