In this research, emphasis has been given on the development of canola oil based polyol by transesterification reaction followed by epoxidation and ring opening by alcoholysis
with the intention of inserting hydroxyl group at unsaturation (carbon-carbon double bond) present in oil.
of glycosyl donors, 4,6-dibenzyloxy-1,3,5-triazin-2-yl (DBT) glycosides 9, under hydrogenolytic conditions gave the corresponding aglycosides 10 in good yields without adding any acid promoters.
The reaction temperatures greater than 60 8C should be avoided, in the case of rubber seed oil, because they tend to accelerate saponification of the glycerides by the alkaline catalyst before completion of the alcoholysis
hydrolysis or alcoholysis
in the presence of an acid catalyst, is a popular method for introduction of hydroxyl groups to vegetable oil.
Two reactions take place during liquefaction: alcoholysis
and recondensation (Zhang et al.
An industrial examples are tin (IV) based compounds FASCAT[R] and LIOCAT[R], which are largely used for the alcoholysis
of vegetable oils with poly-alcohols to prepare alkyd resins (SUAREZ et al.

Introduction of functional groups on the surface of super-paramagnetite particles of M- PVAC without demolishing the magnetite within the particles through several sequential procedures such as alcoholysis
epoxide activation and coupling were subsequently employed .
This property makes possible for them to execute a number of catalytic reactions such as alcoholysis
acidolysis aminolysis esterification and transesterification (Coradi et al.
The Methanol and FFA's can be added to the alcoholysis
reaction to reduce the biodiesel production cost.

During the alcoholysis
or transesterification stage, the oil, polyol.
