    摘要: An improved process for preparing alkanoyloxyacetyloxybenzenesulfonate salts in which phenyl esters of alkanoyloxyacetic acids (alkanoyloxyacetyloxybenzenes) are sulfonated to yield novel alkanoyloxyacetyloxybenzenesulfonic acids which, on neutralization, yield the corresponding alkanoyloxyacetyloxybenzenesulfonate salts.
