NOVELTY - Biodiesel and 1-4C alcohol are produced by providing first input stream (150) comprising syngas; reacting syngas over alcohol-synthesis catalyst for conversion of some syngas to alcohol, thus forming first output stream; providing second input stream (160) comprising triglyceride; combining second input stream with portion of first output stream for transesterification, thus forming second output stream (162) comprising biodiesel, glycerol, and 1-4C alcohol; and separating second output stream into third and fourth output streams.    USE - Method for producing biodiesel and 1-4C alcohol for providing composition useful as diesel fuel or diesel fuel additive (claimed).    ADVANTAGE - The method is capable of producing biodiesel fuels using mixtures of alcohols, which can be produced from syngas over mixed-alcohol catalyst.    DETAILED DESCRIPTION - Producing biodiesel and 1-4C alcohol comprises providing first input stream (150) comprising syngas; reacting syngas over alcohol-synthesis catalyst for conversion of some syngas to alcohol, thus forming first output stream; providing second input stream (160) comprising triglyceride; combining second input stream with portion of first output stream for transesterification, optionally in the presence of an esterification catalyst, thus forming second output stream (162) comprising biodiesel, glycerol, and 1-4C alcohol; and separating second output stream into third and fourth output streams. The third output stream comprises biodiesel and the fourth output stream comprises 1-4C alcohol. An INDEPENDENT CLAIM is included for a composition comprising alkyl esters of fatty acids, in which an average number of carbons contained in the alkyl groups of the alkyl esters is greater than 1.
