| titleOfInvention | Optimized method of pre-treatment of acid waste fat and oil |
| abstract | The optimized method consists in the extraction of fatty acids with alcoholic alkaline solutions, wherein at least one of the volatile organic bases, quaternary ammonium bases and anhydrous ammonia is used as the alkali. As the volatile organic base, at least one alkylamine having a boiling point of not more than 200 degC may be advantageously used, and at least one tetraalkylammonium hydroxide, in particular tetramethylammonium hydroxide, is used as the quaternary ammonium base. From the point of view of the pretreatment process, a process is preferred in which, after distilling off the excess alcohol from the extract, the ammonium salt is dewatered at a temperature in the range of 180 to 220 degC and the resulting amide is converted to the desired fatty acid ester, most often methyl- butyl alcohol in the presence of concentrated sulfuric acid or phosphoric acid. |
