SELECTIVITY AND KINETICS OF INTERESTERIFICATION REACTION OF GLUCOSE PENTAACETATE WITH FATTY ACID METHYL ESTERS
Acetylated glucose fatty esters (AGFEs) were prepared by a solvent-free interesterification reaction of glucose pentaacetate (GPA) and mixed fatty acid methyl ester (FAME) of palm oil (PO)-based fatty acids. The relative selectivity of fatty acyl groups towards the GPA ring and the kinetics of the interesterification process were studied. The selectivity studies have shown that the longer chain fatty acyl groups were preferred in the interesterification process involving GPA and FAMEs. In the C6 to Cl0 fatty acids group C l0 was the most favoured, while C18:1 had the highest selectivity in the C12 to C18:2group. The results also showed that the reactions involving oleic-FAME and C6-10-FAME proceeded via zero-order kinetics with respect to GPAKEYWORDS:
