acrylic acid acryloyl ester - Introduction
Acrylic anhydride is a strong esterifying agent, which is a necessary reagent for the preparation of thioacrylate, acrylamide and methacrylate (especially the ester of tertiary alcohol). At the same time, it can be used as a crosslinking agent for polymerization reaction The synthesis of light-curing coatings, cross-linked resins and other materials can also be used as raw materials for the synthesis of special fine chemicals, and has broad market application prospects.

acrylic acid acryloyl ester - Preparation
At present, the process of synthesizing acrylic anhydride disclosed in the prior art is mainly divided into two categories: the first category is the first synthesis reaction, and the rectification starts after the reaction is completed. Due to the low production efficiency, high energy consumption and high by-products of the first type of synthesis reaction, the second type of batch reaction distillation is generally used to synthesize acrylic anhydride in actual production. Although the efficiency of the second type of batch reaction distillation process is improved compared with the first type of method, it can not overcome the intermittent production mode. The production efficiency and energy consumption are still high, and it is easy to produce by-products, which is not suitable for industrial production./p>
