Procedure

13.6 g (0.04 mol) of 3,4-di-(6-hydroxyhexyloxy)benzoic acid, 9.6 ml (0.06 mol) of N,N-diethylaniline and 100 mg of 2,6-di-tert-butyl-p-cresol as stabilizer are added to 150 ml of 1,4-dioxane and heated to 60° C. At 60° C., 6.9 ml (0.085 mol) of acryloyl chloride are added slowly such that the reaction temperature does not exceed 65° C. The reaction mixture is stirred for 2.5 h at 60° C. The solution is cooled to room temperature and poured onto ice water with stirring. A precipitate of 3,4-di-(6-acryloyloxyhexyloxy)benzoic acid is obtained which is separated by filtration, dried and recrystallized from 300 ml of isopropanol.
