ABSTRACT:
A process for the preparation of a fuel oil (diesel fuel or heating oil) composition which is a mixture of an alkanol tranesterified fatty acid ester triglyceride and an acetal of glycerol is described. The process preferably provides a prestep of the formation of at least some of the alkanol transesterified triglyceride containing the glycerol for use in the formation of the acetal of glycerol. The composition can also be formed from a reaction of 1,1-dimethoxy- or 1,1-diethoxyethane and glycerol to form the acetal in the alkanol transesterified triglyceride.
