Method for producing fatty acid esters |
摘要 |
<p>The invention concerns a method for producing fatty acid esters from fatty acid triglyceride and in particular from animal or vegetable fats and oils by transesterification with a monovalent low-molecular weight alcohol in the presence of a homogeneous or heterogeneous catalyst. In accordance with the invention, the formed fatty acid ester is extracted from the reaction mixture by means of a near-critical extractant. In this way fatty acid esters are obtained at high yield and excellent purity. As the extractant preferably a low pressure gas having a reduced temperature at 20° C. of about 0.7, preferably of equal to or greater than 0.7, is employed. Preferred extractants are carbon dioxide, propane, butane, dimethyl ether, ethyl acetate or mixtures thereof.</p> |
