Participants

Reaction Steps

2000 g of dichloromethane, 40.0 g of 4-hydroxybenzoic acid, 39. 6 g of 4-hydroxybutyl acrylate and 0.05 g of methoquinone were charged into a separable flask of the same type as used in Reference Example 1, and then a liquid mixture consisting of 54.0 g of N,N'-dicyclohexylcarbodiimide, 5.9 g of dimethylaminopyridine and 60 g of dichloromethane was dropwise added thereto at room temperature over 4 hours, while replacing the flask inside gas with a nitrogen gas. After the same treatment as in Reference Example 1, 3.8 g of p-hydroxybenzoyloxybutyl acrylate of the following chemical formula was obtained (yield: 5%): ##STR11##
