The present invention relates to a process for the production of triacetin and alkyl esters of fatty acids, wherein said process comprise the following steps: (i) mixing an alkanolic potassium alkoxide catalyst with vegetable oil and/or animal fat for between 1 and 5 minutes; (ii) reacting said vegetable oil and/or animal fat with an alkyl acetate in the presence of said alkanolic potassium alkoxide catalyst, wherein (a) the molar ratio of vegetable oil and/or animal fat to alkyl acetate is from 1:10 to 1:500; (b) the molar ratio of vegetable oil and/or animal fat to potassium alkoxide is from 1:0.01 to 1:1; and wherein the vegetable oil and/or animal fat, alkyl acetate and alkanolic potassium alkoxide catalyst comprise less than 1000 ppm water; and (iii) separating triacetin and alkyl esters of fatty acids from the resulting reaction mixture. |
