Resumen
The method is applicable to simple and mixed alcohol esters that are liquid at ambient temperature. The following principle is specified: Saponification of the ester using potassium hydroxide in ethanolic solution followed by titration with standard volumetric hydrochloric acid solution in the presence of phenolphthalein as indicator. In the case of mixed alcohol esters the relative molar mass of which can only be estimated the saponification and ester values are used to express the result.
