【Abstract】 A synthesis method of aryl carboxylate esters was reported.It was made from the reaction of sodium 4-phenolsulfonate with Nonanoyl chloride,using Triethylamine as an acid-captor in a one-step process.Triethylamine could absorb hydrogen chloride produced in the reaction,so the reaction speed was accelerated greatly.The factors affecting the preparation of aryl carboxylate esters were investigated.At optimal conditions,the yield reached 89 % and esteraselevel 98 %.The product was characterized by IR and HLPC analysis method.更多还原
