- 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.

- Chemoselective Transesterification of Acrylate Derivatives for Functionalized Monomer Synthesis Using a Hard Zinc Alkoxide Generation Strategy
-
A new practical method for the synthesis of functionalized acrylate derivatives with the view to prepare functional polymers was explored. Hard zinc alkoxide generation enabled the highly chemoselective transesterification of acrylate derivatives over the undesired conjugate addition, which caused polymerization. The combined use of the catalytic zinc cluster Zn4(OCOCF3)6O and 4-(dimethylamino)pyridine delivered various functionalized acrylate derivatives through the transesterification of commercially available methyl acrylate derivatives with functionalized alcohols under mild conditions.

- 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.
