| 摘 要： | 本工作以苯甲酰甲酸(BF)和2-羟基-2-甲基-对羟乙基醚基苯基丙酮(2959)为原料,通过酯化反应合成了一种光引发剂BF-2959,采用紫外、红外、核磁共振、元素分析等手段对其进行了表征。研究了光引发剂BF-2959的合成条件,得到最佳实验条件:以甲苯为溶剂,反应时间6h,反应温度105℃,以甲烷磺酸为催化剂,苯甲酰甲酸与2959的物质的量投料比为1∶1.1,产率为92.1%;产物为无色透明液体,与树脂的相容性较好,紫外最大吸收峰在246.1nm处。在涂膜光固化测试中,用4%的BF-2959引发B-206聚氨脂和TMPTA单体聚合,转化率为93%。

| Abstract: | With phenylglyoxylic acid and 2959 as raw materials,a novel photoinitiator (BF-2959) was synthesized by esterification,and characterized by UV,FTIR,NMR and elemental analysis.The optimized synthetic conditions of BF-2959 is that phenylglyoxylic acid and 2959 mole ratio is 1 ∶ 1.1 and dissolved in toluene with methanesulfonic acid as catalyst,when react at 105 ℃ for about 6 h,then the yield is 92.1％.The product is colorless and transparent liquid,and the compatibility with resins is good.The maximum ultraviolet absorption peak is at 246.1 nm.In the UV coating test,the optimum dosage of BF-2959 was 4％,the conversion rate of the B-206 polyurethane resins and TMPTA monomer polymerization was 93％. |
