摘　　要：以6-羟基-2-萘甲酸和对位烷基取代苯酚为原料,合成了4种新型萘基偶合剂6-羟基-2-萘甲酸（4-烷基）苯酯,优化了合成过程中的重要参数,其最佳合成条件为：以甲苯为溶剂,三氯化磷为脱水剂,醇酸摩尔比为1.2∶1,脱水剂用量为原料酸的34%～37%（摩尔分数）,加热回流5h,收率60%～90%。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6-羟基-2-萘甲酸（4-丙基苯）酯是一种较理想的偶合剂。A novel naphthyl coupling agent,6-hydroxy-2-naphthoic acid（4-Alkyl）phenylester,has been prepared using 6-hydroxy-2-naphthoic acid and 4-alkylphenol.The parameters that had effect on the synthesis were optimized in detail.The optimal conditions for synthesis：using toluene as solvent,PCl3 as a catalyst,molar ratio of alcohol to acid is 1.2∶1,the amount of catalyst is 34%-37%（molar ratio）of raw material acid,heated to reflux for 5h,yield 60%-90%.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 6-hydroxy-2-naphthoic acid（3-propyl）phenylester is an ideal coupling agent.
