| titleOfInvention | An optimized way to pre-treat acid waste fats and oils |
| abstract | The optimized process consists in extracting the fatty acids with alcoholic alkaline solutions, using at least one of the volatile organic bases, quaternary ammonium bases and anhydrous ammonia as alkali. Preferably, at least one alkylamine having a boiling point not exceeding 200 degC is used as the volatile organic base, and at least one tetraalkylammonium hydroxide, especially tetramethylammonium hydroxide, as the quaternary ammonium base. From the point of view of the pre-treatment process, the preferred method is to dewater the ammonium salt from the extract by distilling off the excess alcohol at a temperature in the range of 180 to 220 degC and converting the resulting amide into the desired fatty acid ester, most often methyl, ethyl or butyl alcohol in the presence of concentrated sulfuric or phosphoric acid. |
