Abstract

Abstract:

A new kind of benzo[b]thiophen-2-yl(phenyl)methanone was prepared by benzothiophene with benzoyl chloride. The optimum reaction conditions were determined. It showed that the yield of target product was 72% when the reaction was carried out under microwave irradiation (30 W) for 15 min in N, N-dimethylformamide (DMF). Further, the photo-initiated polymerization performance test of the title compound show that it can be applied as radical photoinitiators in UV-curing system. The UV-curable coating has good reaction activity, surface curing capability. And the release of benzene is also reduced.

Key words: phenyl benzothiophene ketone, benzothiophene, UV-curing, photoinitiators, microwave irradiation
