摘要
以氟苯为原料 ,经Friedel-Crafts酰化、α 卤代、环氧化、季铵化及Stevens重排和亲核取代反应 ,合成了 3种未见报道的α 氨基苯乙酮衍生物光引发剂 :1 对吗啉苯基 2 哌啶基 2 烯丙基 1 丁酮、1 对吗啉苯基 2 哌啶基 2 苄基 1 丁酮和 1 对哌啶苯基 2 哌啶基 2 烯丙基 1 丁酮。对产物的结构进行了表征 ,并将其用于清漆和色漆中 ,测试了光引发性能 ,实验结果表明 ,3种产物均能使涂层在 8~ 2 5s内固化 ,光引发性能优良。
Three photoinitiators of αaminoacetophenone derivatives 1(pmorpholinophenyl)2piperidyl2allyl1butanone,1(pmorpholinophenyl)2piperidyl2benzyl1butanone and 1(ppiperidylphenyl)2piperidyl2allyl1butanone,which had not been yet reported,were synthesized with FriedelCrafts acylation,αhalogenation,epoxidation,quaternization,Stevens rearrangement and nucleophilic substitution from fluorobenzene.The structures of these products were characterized.Then the compounds were added to clear and pigmented paint to test their photoinitiability.The test demonstrated excellent photoinitiability of all three products which can cure paint layer within 8-25 s.
