以壬酸和醋酸乙烯酯为原料,硫酸汞为催化剂,通过乙烯基交换反应制备了壬酸乙烯酯。采用气相色谱研究了原料配比、催化剂用量、反应时间对产率的影响,建立了内标法检测分析方法,并以气质联用及核磁共振对产物的结构进行了分析和表征。结果表明,当壬酸与醋酸乙烯酯物质的量比为1∶7,催化剂用量为原料总质量的1.5%,反应时间为6 h时,产物产率达92%以上。 Nonanoic acid and vinyl acetate as raw materials, mercuric sulfate as a catalyst, prepared by the vinyl exchange reaction of nonanoic acid vinyl ester. The effects of the ratio of raw materials, the amount of catalyst and the reaction time on the yield were studied by gas chromatography. The internal standard method was established for detection and analysis. The structure of the product was analyzed and characterized by GC / MS. The results show that when the molar ratio of nonanoic acid to vinyl acetate is 1: 7, the amount of catalyst is 1.5% of the total mass of the raw material and the reaction time is 6 h, the yield of the product is over 92%.
