1, 4-bis(chloromethyl)benzene synthesis technology
2015
The invention relates to a 1, 4-bis(chloromethyl)benzene synthesis technology and belongs to the technical field of organic chemical synthesis. The technology comprises that under LED light source irradiation, p-xylene and chlorine undergo a reaction in the presence of an ionic liquid catalyst to produce a 1, 4-bis(chloromethyl)benzene reaction solution, the 1, 4-bis(chloromethyl)benzene reaction solution is cooled and separated so that a 1, 4-bis(chloromethyl)benzene crude product is obtained, and the 1, 4-bis(chloromethyl)benzene crude product is subjected to vacuum rectification so that 1, 4-bis(chloromethyl)benzene is obtained. The 1, 4-bis(chloromethyl)benzene has a melting point of 98-101 DEG C and purity of 99% or more. The 1, 4-bis(chloromethyl)benzene synthesis technology is free of any solvent, guarantees high product purity, has the characteristics of high conversion rate, fast reaction rate and low cost and is suitable for industrial production.
