Benzyl acrylate (CAS 2495-35-4)

Benzyl acrylate, an unsaturated monomeric ester resulting from the combination of acrylate acid and benzyl alcohol, presents as a colorless and transparent liquid with a mild odor. This versatile compound finds extensive application in the production of polymers, adhesives, coatings, and inks. The synthesis of benzyl acrylate is relatively straightforward, achieved through the reaction of acryloyl chloride and benzyl alcohol, utilizing pyridine as a catalyst. However, this reaction requires careful temperature and time management due to its highly exothermic nature, generating a significant amount of heat. The applications of benzyl acrylate span various scientific research areas, including polymer synthesis, drug delivery, and tissue engineering. As a reactive monomer, it plays a pivotal role in crafting polymer and copolymer systems, facilitating the creation of compounds like polyacrylamide, polyacrylic acid, and polyacrylate. Furthermore, its role extends to the preparation of acrylic resins, widely employed in coatings and adhesives. Additionally, benzyl acrylate has found use in developing drug delivery systems, such as liposomes and nanoparticles. Being an unsaturated monomer, benzyl acrylate exhibits versatility in participating in a range of chemical reactions. The most common reaction it undergoes is polymerization, where monomers unite to form sturdy polymer chains. This process is initiated by various catalysts like peroxides or UV light. During polymerization, the acrylate groups within benzyl acrylate interlink, creating strong and stable covalent bonds essential for the formation of the polymer chain.
