METHOD FOR PREPARING ACRYLATE COMPOUND

摘要

The present invention relates to a method for preparing an acrylate compound. The acrylate compound has a structure as shown in formula (I). The method includes: subjecting a compound with a structure of formula (II) or a mixture of compounds with structures of formula (I) and formula (II), and a catalyst to a contact reaction in the absence of an anhydride, and removing the resulting methanol by pressure reduced distillation during the contact reaction process. In the formulas (I) and (II), R is selected from one of: an alkoxy with a carbon number of 1-5, a substituent-containing phenoxyl with a carbon number of 6-20, a substituent-containing heteroaryloxy with a carbon number of 4-20, a substituent-containing heteroaryloxymethyl with a carbon number of 4-20, a substituent-containing phenoxymethyl with a carbon number of 5-20, and a substituent-containing alkyl with a carbon number of 2-20. According to the method for preparing an acrylate compound provided in the invention, the conversion rate and selectivity of the reaction can be substantially improved.
