摘要:

以2-巯基苯甲酸和苯酚为原料,在浓硫酸的催化作用下合成了2-羟基硫杂蒽酮(TX1),然后合成了2-羟基-3-(2-硫杂蒽酮氧基)丙基三甲基氯化铵(TX2)光引发剂。讨论了制备过程中投料比、温度和pH值等因素对光引发剂产率的影响,并通过红外光谱、核磁共振和元素分析等方法验证了所合成的光引发剂的结构。对比当前市售的Iragcure184D(α-羟基酮类光引发剂)等光引发剂,进一步研究了合成的两种光引发剂的水溶性和感光性。

Abstract:

2-Hydroxy-thioxanthone (TX1)was prepared with thiosalicylic acid and phenol as reactants and concentrated sulfuric acid as catalyst, which was converted to 2-hydroxy-3-(9-oxo-9H-thiox-anthen-2-yloxy)-propyl-trimethyl-ammonium chloride (TX2).The influence of feed ratio, temperature and pH value on the yield of products was discussed.The structure of products was proved by means of FTIR, NMR and elemental analysis.The water-solubility and photo-sensitivity of prepared TX1 and TX2 were investigated by comparing with the commercial photoinitiator Iragcure184D(α-hydroxyketone photoinitiator).
