摘要:

以3-羟基-2-萘甲酸、端羟基直链烷烃二醇为原料,合成了一种新型萘基偶合剂3-羟基-2-萘甲酸(1,n-烷二醇)二酯,考察了合成过程中的影响因素,最佳合成条件为:以甲苯为溶剂,三氟甲磺酸为催化剂,醇酸摩尔比为1∶2,催化剂用量为原料酸的5%(摩尔比),加热回流5h.通过元素分析、NMR、质谱等手段对产物进行了结构表征,并对其感光性能进行了初步研究.结果表明3-羟基-2-萘甲酸乙二醇二酯是一种较理想的偶合剂.

A novel naphthyl coupling agent,3-hydroxy-2-naphthoic acid（1,n-Alkylene glycol）diester,has been prepared with 3-hydroxy-2-naphthoic acid and hydroxyl-terminated alkane.The parameters that had effect on the synthesis were optimized in detail.The optimal conditions for synthesis：using toluene as solvent,three trifluoroacetic acid as a catalyst,molar ratio of alcohol to acid is 1∶2,the amount of catalyst is 5%（molar ratio）of raw material acid,heated to reflux for 5h.The structure of target coupling agent was characterized with Element analyzer,NMR and Mass Spectrometry.The photosensitive property of the product was preliminarily investigated.The results show that 3-hydroxy-2-naphthoic acid glycol diester is an ideal coupling agent.
