摘要： 1-蔡乙酸是一种植物生长调节剂,也是合成蔡乙酸甲醋(另一种优良的植物生长调节剂)的原料.其合成方法有多种[1,2].本文研究了在常压下,利用Co2(CO)8.在相转移催化条件下,使1-氯甲基蔡和一氧化碳直接反应,转化为茶乙酸的合成方法,气相色谱分析法研究了反应温度、催化剂用量等反应条件对转化率的影响.

Abstract: 1-Naphthalene acetic acid was synthesized from 1-chloromethyl naphthalene byoctacarbonyl dicobalt under phase transfer catalytic conditions.Conversion was 99% andyield 83%.The effects of reaction temperatures, ratios of reactants, solvents, contents ofcatalyst and concentration of alkali on conversion have been investigated.Among the phasetransfer catalysts tested, the most effective was hexadecyltrimethylammonium chloride.

Key words: naphthaleneacetic acid, synthesis, chloromethyl naphthalene, phase transfer catalysis, octacarbonyl cobalt
