PROCESS FOR SYNTHESIS OF POLYOL FATTY ACID POLYESTERS

摘要

A PROCESS FOR PREPARING ESTERIFIED POLYOL FATTY ACID POLYESTERS IS PROVIDED, WHERE THE POLYOL HAS N HYDROXYL GROUPS. THE PROCESS PROVIDES FOR INDEPENDENT CONTROL OF THE LEVEL OF FULLY ESTERIFIED POLYOLS ON THE ONE HAND, AND THE LEVEL OF N-3 AND LOWER ESTERS, ON THE OTHER HAND. THE PROCESS IS ESPECIALLY SUITED FOR PREPARING SUCROSE POLYESTER, WHEREIN THE PROCESS PROVIDES FOR INDEPENDENT CONTROL OF THE LEVEL OF OCTAESTERS, ON THE ONE HAND, AND PENTA AND LOWER LEVEL ESTERS, ON THE OTHER HAND. THE PROCESS CAN BE USED TO REDUCE THE LEVEL OF UNDESIRABLE REACTION BYPRODUCTS, SUCH AS DIFATTY KETONE AND BETA KETOESTER.
