A kind of reactor and reaction system for synthesizing methyl butynol

Abstract

The invention discloses a reactor and reaction system for synthesizing methylbutynol. The reactor comprises a first-stage tubular reactor and a second-stage tubular reactor, which are connected sequentially, wherein each of the first-stage tubular reactor and the second-stage tubular reactor comprises a tubular reactor and a static mixer arranged in the tubular reactor. The reaction system comprises a stirring reaction kettle, a reactor and a termination mixer which are connected in a proper sequence by virtue of pipelines, wherein the reactor adopts the above reactor for synthesizing methylbutynol, a discharge port of the stirring reaction kettle is connected with a feed port of the first-stage tubular reactor, and a discharge port of the second-stage tubular reactor is connected with a feed port of the termination mixer. The reactor and the reaction system for synthesizing methylbutynol, disclosed by the invention, not only greatly shorten the tube pass length of the reactor, but also realize effective mixing of materials, avoid occurrence of side reactions, and greatly improve the product yield in comparison with an early process.

Description

technical field [0001] The invention belongs to the technical field of organic chemical industry, and more specifically relates to a novel reactor and a reaction system for the production of methyl butynol. Background technique [0002] Methylbutynol is one of the important acetylenic alcohol chemicals, mainly used in corrosion inhibition, food and medicine, and other chemical products and other fields. The early relevant patents were mainly from Italy Slam (SNAM), such as Italian patents IT590732, IT650164, IT778013, IT684731, IT692788, IT695546, etc., US patents US3283014, US3301771, etc., British patents GB902014, GB93563, GB938849, GB1041052, GB55 , GB938849, etc., and domestic patent CN104470879A, etc. [0003] Studies have shown that the main reaction of acetylene and acetone to synthesize methyl butynol is an exothermic reaction, the heat of reaction ΔH°298=-62.76kJ / mol, the reaction is about 1st order for acetylene, and about 1.5th order for catalyst, and the produc...

AI Technical Summary

Problems solved by technology

[0003] Studies have shown that the main reaction of acetylene and acetone to synthesize methyl butynol is an exothermic reaction, the heat of reaction ΔH°298=-62.76kJ / mol, the reaction is about 1 level for acetylene, about 1.5 level for catalyst, and the product methyl Butynol is easy to react with acetone to form dimethylhexynediol, which leads to a decrease in the selectivity of methylbutynol
