Abstract

The process of diene cyclization of 2,3-dimethylbutadiene with 2-hydroxyethylmethacrylate was investigated. Effects of temperature, reaction duration, and ratio of reagents on the yield of 2-hydroxyethyl-1,3,4-trimethylcyclohex-3-encarboxylate was studied. Optimal conditions of passing the process were found. Kinetic regularities of 2-hydroxyethyl-1,3,4-trimethylcyclohex-3-encarboxylate obtaining has been investigated. On the basis of the obtained results the optimal conditions of the target product synthesis have been established.
