Abstract:
1. A process for producing mixed esters of fatty acids, the method comprising: (a) partially transesterifying at a temperature between about 50° C. and 200° C. and a pressure between about 0.5 atm and 20 atm (i) a mixture of fatty acid methyl esters, the mixture being free from fatty acid alkyl esters with alkyl ester groups containing 2 or more carbon atoms, with (ii) at least one alkyl alcohol containing 2 to 8 carbon atoms in the presence of a heterogeneous solid acid catalyst to produce a mixture of fatty acid alkyl esters comprising at least some fatty acid methyl esters and at least some fatty acid alkyl esters with alkyl groups containing 2 to 8 carbon atoms; and (b) separating the produced mixture of fatty acid alkyl esters from the heterogeneous solid acid catalyst.
