摘要:

以苯并噻吩为原料,通过酰基化反应,在噻吩环上引入苯甲酰基,制备了苯基苯并噻吩酮。通过高效液相色谱分析法,分别对微波辐射和传统油浴加热条件下的反应结果进行了测试,结果表明:当微波输出功率为30 W、催化剂为AlCl3、反应时间为15 min、溶剂为DMF时,产率可达72%。该化合物的紫外吸收红移到359 nm,作为紫外光固化涂料中的光引发剂,表现出良好的反应活性、表面固化能力及溶解性。

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
