摘要： A method of producing an alkyl ester of a carboxylic acid is provided, the method comprising: adding an alkanol and a mineral acid to a carboxylic acid salt to provide a carboxylic acid/alkanol solution and a precipitated mineral acid salt; separating the mineral acid salt from the carboxylic acid/alkanol solution; esterifying the carboxylic acid; and isolating an alkyl ester of the carboxylic acid.

摘要： 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 transesterif ied 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, l-diethoxye thane and glycerol to form the acetal in the alkanol transesterif ied triglyceride.
