噻吨酮酰胺类光引发剂的合成及性能

Studies on Synthesis of Photoinitiator of Thioxanthone Carboxylic Amides and Their Properties

合成了１２个噻吨酮酰胺类光引发剂，它们均为新化合物。经红外光谱、质谱及元素分析等方法确证结构。采用膨胀计法研究了它们的光引发性能，并和其它种类（如烷基）取代的噻吨酮作了比较。结果发现取代基的位置和结构对引发性能有一定影响。

Twelve thioxanthone carboxylic amides have been synthesized. They are new compounds. The structures of these compounds were identified by IR, MS and elementary analysis. Photoinitiative properties were studied by means of dilatometric method. It is observed that the kind of substituents and their positions have influence on photoinitiative properties of thioxanthones.
