Abstract of the disclosure: A process is described for preparing carboxylic acid esters of hexitols by rapidly heating the hexitol and carboxylic acid to 210 to 250°C in the presence of alkaline catalysts, continuing the esterification reaction at this temperature, while simultaneously driving off the water formed, until an acid number of 2 to 15 has been reached, and then rapidly cooling down to at least 145°C. This process produces hexitol carboxylates which are essentially free of anhydro compounds and have good color quality. The hexitol carboxylates are surface-active substances, in particular high-grade emulsifiers and lubricants.
