Notes:
Sorbitan esters were prepared by controlled dehydration of sorbitol followed by lipase-catalyzed esterification of the resulting “sorbitan.” The reaction was carried out in azeotropic mixtures of tert-butanol/n-hexane. A partial phase diagram to determine the temperature required for the distillation of the azeotrope at a given ratio of the solvents was constructed. The effect of varying concentrations of the two solvents on the rate of esterification and the monoester/diester ratio of the final product was investigated in detail. © 1997 John Wiley & Sons, Inc.
