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.
Application
Acrylic anhydride (CAS 2051-76-5) is a highly reactive difunctional monomer containing two acryloyl groups, making it an efficient crosslinking agent and acylating reagent. It is widely used in the synthesis of acrylic polymers, copolymers, and functional resins for coatings, adhesives, sealants, and UV-curable formulations. As a crosslinker, it introduces pendant vinyl groups into polymer backbones, enabling subsequent free-radical or photoinitiated curing. In organic synthesis, it serves as a mild and selective acryloylating agent for alcohols and amines, producing acrylate esters and acrylamides without the need for activating agents like carbodiimides or acid chlorides. It is also employed in the preparation of hydrophilic hydrogels, dental materials, and biomedical adhesives. Additionally, acrylic anhydride finds use in the modification of natural polymers (e.g., cellulose, starch) for biodegradable plastics and in the synthesis of specialty monomers for water treatment and personal care products. Its high reactivity requires careful handling under anhydrous conditions.
