- O-PHENYL PHENOXYALKYL ACRYLATE AND METHODS FOR PRODUCING THE SAME
-
The present disclosure provides a method for preparing o-phenyl phenoxyalkyl acrylate, including: transesterifying an acrylate-based compound with a biphenyl alcohol compound in the absence of a solvent and in the presence of a catalyst and a polymerization inhibitor to prepare the o-phenyl phenoxyalkyl acrylate represented by the following formula (II), wherein the catalyst is a compound containing a tin element or a titanium element. According to the method of the present disclosure, the o-phenyl phenoxyalkyl acrylate having transparency and high refractive index can be obtained. Moreover, the method of the present disclosure has the characteristics of high conversion rate and high selectivity, and does not need to add other organic solvents, so that many purification processes can be saved, and the production cost is effectively reduced, which has the value of industrial application.
