新型水溶性硫杂蒽酮类光引发剂的合成

SYNTHESIS OF WATER SOLUBLE PHOTOINITIATORS OF THIOXANTHONE DERIVATIVES

合成了４种季铵盐类硫杂蒽酮化合物。其中２羟基（１’甲基４’硫杂蒽酮氧基）Ｎ，Ｎ，Ｎ三甲基丙基氯化铵为新化合物。这些化合物均经过了ＩＲ、ＮＭＲ、ＭＳ和元素分析等方法鉴定，确证了其结构，还测定了紫外吸收光谱。

Four photoinitiators of water soluable thioxanthone derivatives were synthesized. 2 hydroxy 3 (1 methyl 9 oxo 9H thioxanthone 4 yloxy) N,N,N trimethyl 1 propanamonium chloride is a new compound which was not reported. These compounds were identified by IR, NMR, MS and Elemental analysis etc. and the UV absorption wavelength and the molar absorption coefficient were determined.
