Problems solved by technology

[0004] Because calcium carbonate and other carbonates are used in the process of the above method, the amount of solid waste produced in the whole process is large, which is not easy to deal with in the later stage and causes great environmental pollution; moreover, this treatment process makes the product unstable and easily produced by colorless Easy to turn black, there is a problem of discoloration

Abstract

The invention relates to the field of chemical production systems, in particular to a monochloroacetone production system which comprises a rectification assembly, the rectification assembly is connected with upstream monochloroacetone process equipment, a liquid phase collection assembly is installed at the lower end of the rectification assembly, and a gas phase collection assembly is installed at the upper end of the rectification assembly. A feeding pipeline is connected to the outer side of the middle part of the rectification assembly, and the rectification assembly is used for distilling materials conveyed by the feeding pipeline and realizing gas-liquid separation. Aiming at the problems of large solid waste amount, color change and the like in the prior art, the system improves a new rectification mode, can achieve the purpose of direct purification without using calcium carbonate, and the purity can reach the industrial standard: 98% and the dye grade: 90%; according to the system, efficient purification is realized by adopting a bubbling and two-stage rectification mode, and monochloroacetone produced by utilizing the system is stable in chromaticity and is generally colorless to yellowish; and the solid waste amount in the whole process is greatly reduced.

Description

technical field [0001] The invention relates to the field of chemical production systems, in particular to the production system of monochloroacetone. Background technique [0002] Chloroacetone decomposes under the action of sunlight to form a gas with strong lachrymatory properties. It is a kind of lachrymatory poison. It is a colorless liquid with a pungent smell. Melting point (°C): -44.5, boiling point (°C): 120 ; Soluble in water, soluble in ethanol, ether, chloroform; It is mainly used as an insecticide, lachrymator, and also used in the preparation of drugs, etc.; used as an intermediate in organic synthesis, used in the production of drugs, etc., insecticides, Spices, dyes, desiccants, antioxidants and vinyl photosensitive resins, etc. It is also a reagent in the Feist-Benary synthesis of the furan ring system. [0003] At present, when monochloroacetone is purified, it needs to be processed with carbonates such as calcium carbonate. For example, in the patent app...
