Synthesis Of (3,4-Epoxycyclohexyl) Methyl Methacrylate

3-Cyclohexenylmethyl methacrylate was synthesized by transesterification using methyl methacrylate and 3-cycloexene-1-methanol as raw materials. The effects of the factors such as catalyst type, catalyst amount, raw material ratio, reaction time,inhibitor type and amount on reaction results were investigated. The obtained optimum reaction conditions were using Organotin as catalyst, m?Organotin?:m?3-cycl-ohexene-1-methanol?=0.06, inhibitor 1 as inhibitor, m?inhibitor1?:m?3-cyclohexene-1-methanol?=0.001, reaction time 5h, reaction temperature105-120 ?, raw materal ratio n?MMA?:n?3-cyclohexene-1-methanol?=3:1. Under above conditions, the conversion of 3-cyclohexene-1-methanol was> 97 %, while the product yield was> 94 %. The structure of the product was characterized by FT-IR and ¹H NMR.3-Cyclohexenyl methacrylate was synthesized by transesterification using methacrylate and 3-cycloexene-1-methanol as raw materials.
