Abstract

This experiment was to determine the optimum conditions for D-sorbitol cyclization in the presence of p-toluenesulfonic acid(p-TSA) as acid catalyst before the esterification of sorbitol with fatty acids. The optimum conditions of hydration reaction to obtain maximum yield of 1,4-sorbitan were at $130^{\circ}C$, 200mmHg reduced pressure, after l50min and l%(w/w) p-TSA. In this condition the yield of 1,4-sorbitan was approximately 90%.
