Chiral epoxypropane continuous production device

Abstract

The invention provides a chiral epoxypropane continuous production device which comprises a reaction kettle, a control panel, a post-reaction flow guide pipe, a drainage pipe, a control valve I, a buffer tank, a conveying pipe, a control valve II, a condenser, a discharge pipe and a control valve III, and the left lower side of the reaction kettle is in screw connection with the control panel; and one end of the post-reaction flow guide pipe is in threaded connection with the right lower outlet in the reaction kettle, and the other end is in threaded connection with the left end of the drainage pipe. Through the arrangement of a feeding hopper, an impurity collecting box, a feeding guide pipe, an impurity filtering net, a baffle with a ring and an adsorption piece, impurity filtering can be conducted on raw materials, iron impurities can be adsorbed, the treatment effect is guaranteed, the raw materials are introduced through the feeding hopper, impurity filtering is conducted through the impurity filtering net, impurities are collected through the impurity collecting box, and after the raw materials are adsorbed through the adsorption piece, the baffle with the ring is lifted up, at the moment, the raw materials enter the reaction kettle through the feeding guide pipe, and processing production operation is started.

Description

technical field [0001] The invention belongs to the technical field of continuous production equipment of propylene oxide, in particular to a continuous production device of chiral propylene oxide. Background technique [0002] Propylene oxide, also known as propylene oxide and methyl oxirane, is a very important organic compound raw material and the third largest propylene derivative after polypropylene and acrylonitrile. Propylene oxide is a colorless ether-like liquid with a low boiling point and is flammable. There is chirality, and the industrial product is generally a racemic mixture of two enantiomers. [0003] At present, chiral propylene oxide continuous production devices are widely used. [0004] However, the existing continuous production device still has the problems that the uneven mixing of raw materials affects the production efficiency, the dirty air intake affects the processing efficiency, the chiral propylene oxide cannot be pre-filtered and the materia...
