1-对甲硫基苯基-2-甲基-2-吗啉基-1-丙酮的合成与应用

摘要

The photoinitiator 2-methyl-1-［4-(methylthio)phenyl］-2-morpholino-1-propanone(Ⅰ) purity of 99.6% was synthesized form morpholino and 1-methoxy-1-［4-methylthiophenyl］-2,2-dimethyl-epoxy ethane in reflux for 16 h, which prepared by αbromoketone and sodium methylatein methanol. The yield of the product was up to 84.6%. Curing rate of the UV coation with Ⅰ is faster than that with 1,3dimethoxy benzene under air and oxygen insulation.%以α-溴代酮和甲醇钠为原料,甲醇为溶剂合成了中间产物1-甲氧基-1-对甲硫基苯基-2,2-二甲基环氧乙烷；回流状态下,使该中间产物与吗啉反应,合成了题述产物,纯度99.6%,总收率84.6%。并用其制UV固化涂料时,在空气和绝氧条件下,固化速度优于安息香二甲醚。
