- Method for preparing (methyl)acrylic acid-3,4-epoxycyclohexyl methyl ester by microchannel reactor
-
The invention discloses a method for preparing (methyl) acrylic acid-3,4-epoxycyclohexyl methyl ester by a microchannel reactor. The method is characterized in that firstly, 3-cyclohexene-1-methanol and (methyl)acryloyl chloride are used as raw materials; esterification reaction is performed in the microchannel reactor to prepare an intermediate of (methyl)acrylic acid-3-cyclohexenyl methyl ester;then, peroxyacetic acid is used as an oxidizing agent; chlorohydrocarbon is used as a reaction medium; selective epoxidation reaction is performed in the microchannel reactor to prepare a target product. The esterification reaction temperature is low; the side reactions are few; the efficiency is high; the aftertreatment is simple; an in-situ method is used; peroxyacetic acid is prepared; meanwhile, olefin epoxidation reaction is performed; the technological process is easy to operate; the reaction yield is high; the product purity is high; the operation of the product separation process is simple; the method is suitable for continuous production; when a curing resin composition prepared by the product is used, a good cured matter with high sealing performance and chemical resistant performance on a base material can be obtained, and can be suitable for being used in the field of electronic materials.

- SYNTHESIS AND STRUCTURE OF ACRYLOYLOXYMETHYL- AND 1-ACETOXYMETHYL-3,4-EPOXYCYCLOHEXANES
-
1-Acryloyloxymethyl- and 1-acetoxymethyl-3,4-epoxycyclohexanes were synthesized, and their structures were studied.It was shown that these compounds are cis- and trans-epoxy conformers and can take part in complex formation with acrylonitrile and with certain polar solvents.
