ABSTRACT:
Sorbitan fatty acid esters are prepared by forming anhydro sorbitol (a mixture of sorbitans, isosorbide, and unreacted sorbitol) by acid-catalyzed anhydrization, then reacting the resulting anhydro sorbitol with a fatty acid in the presence of a base at a temperature not exceeding about 215.degree. C. Use of temperatures not over 215.degree. C. results in products having substantially less color than those obtained at higher temperatures.
