ABSTRACT:
Sugar esters are separated and purified by forming an aqueous mixture containing salt from which water is distilled off to remove unreacted volatile material from the raw sugar esters. Thereafter an organic extraction solvent is mixed into the aqueous mixture which upon standing separates into a plurality of layers containing sugar esters of different degrees of substitution which are recovered from the separated layers. The separated sugar esters may be further refined by mixing with water and by freeze drying the aqueous mixture.
