| Abstract: | The ethyl esteriiications of C1-C8 fatty acids and lactic acid in the presence of N, N-Dimethyl Acetamide arc studied. The yield of Estcrification products is above 95%. The separation of the products was carried can on the column packed with 10% Polyethylene Glycol Succinate.The method is suitable for the Gas-Chrornatogranhic determination of C1-C3 fatty acids and lactic acid in drinks, food and fermentative products. |
