A direct, essentially one-step method of preparing nuclearly chlorinated naphthalene esters which comprises forming a reaction mixture consisting essentially of a mono- or dicarboalkoxy substituted naphthalene, a chlorinated organic solvent having from 1 to 4 carbon atoms and a chlorination catalyst, heating the reaction mixture, and passing molecular chlorine into the mixture. The extent of the chlorination of the naphthalene mono- or diester can be controlled by varying the solvent employed, the amount of chlorine added and the reaction time. A number of unreported polychlorinated naphthalene esters and an acid chloride are obtained directly by the method. The esters can be used in the production of coloring materials, plastics and insecticides.
一种直接、基本上一步法制备核氯化萘酯的方法,包括形成反应混合物,其基本上由单或双碳酰烷氧基取代的萘、具有1至4个碳原子的氯化有机溶剂和氯化催化剂组成,加热反应混合物,并将分子氯通入混合物。萘单酯或二酯的氯化程度可以通过改变所用的溶剂、加入的氯量和反应时间来控制。该方法直接获得了许多未报告的多氯化萘酯和酸氯化物。这些酯可以用于生产着色材料、塑料和杀虫剂。
