摘　　要：在相转移催化剂作用下进行了松香树脂酸钠和氯丙烯合成树脂酸烯丙酯的反应研究,考察了反应温度、反应时间、催化剂种类、催化剂用量、溶剂用量以及物料配比等因素对合成反应的影响。结果表明,优化的反应条件是:树脂酸钠与氯丙烯的摩尔比为1∶2.5,催化剂十六烷基三甲基溴化铵用量为树脂酸钠质量的3%,反应温度45℃,反应时间7h,产品收率为90.2%,经GC分析纯度为98.92%,结构通过IR、GC-MS确证。A phase transfer catalysis （PTC） reaction was studied to synthesize allyl resinate from sodium resinate and allyl chloride, in which the factors influencing the yield of the reaction, such as reaction temperature, reaction time, catalyst type and dosage, amount of solvent and molar ratio were investigate. Under the optimum reaction conditions： reaction temperature 45 ℃, molar ratio of sodium resinate to allyl chloride 1 ： 2.5, amount of catalyst hexadecyl trimethylammonium bromide 3% based on the sodium resinate, and reaction time 7 h, the yield of product was 90.2% with purity of 98.92% （CJC）. The structure of product was characterized by IR and GC-MS.
