Esterification reactor

Abstract

The invention relates to an esterification reactor, comprising a barrel body, an upper end closure and a lower end closure which are fixed on two ends of the barrel body, wherein the upper end closure is provided with an inlet distributor, a safety valve port and an air discharging outlet; the inlet distributor is provided with a material inlet; the exterior of the lower end closure is provided with an unloading outlet, a material outlet and a pressure gauge pipe orifice; an outlet collector is fixed on a position in the lower end closure correspondingly to the material outlet; the outer wall of the barrel body is provided with a differential pressure gauge pipe orifice, a thermometer pipe orifice, a pressure gauge pipe orifice and an agent discharging outlet; the interior of the barrel body is provided with a catalyst layer and ceramic balls with different diameters; and the middle part of the inner wall of the barrel body is downwards provided with a compression ring board, a metal silk net, a support ring board, a grid board and a support board orderly. According to the invention, material is dispersed through the inlet distributor so as to realize even distribution of the material; then, the material is reacted from a preheating section containing the ceramic balls to a reaction section containing catalyst; thus, an esterification converting ratio is increased greatly; and the esterification reactor has very good economic benefit and social benefit.

Description

technical field [0001] The invention relates to an esterification reactor for producing sec-butyl acetate. Background technique [0002] Second-butyl acetate is a colorless liquid, insoluble in water, miscible in most organic solvents such as ethanol and ether, used as solvent, chemical reagent and spice preparation. The existing esterification reaction for the production of sec-butyl acetate is to install a stirring rod in the jacketed reactor shell, and set a guide tube near the stirring rod. Although it has a certain conversion rate, it has high requirements for the material of the stirring rod. The cost is high, and due to the coil heat exchanger, the heat transfer efficiency is low, the space is large, and the structure is complex and cumbersome. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides an esterification reactor with simple structure and long service life. [0004] In order to achieve the above object,...
