| titleOfInvention | Method for extracting lower fatty acid |
| abstract | PURPOSE: To extract efficiently a lower fatty acid from a dilute aqueous solution of the lower fatty acid, by using a specific mixed solvent, having a low viscosity, scarcely forming an emulsion, capable of reducing the separation time and exhibiting a high partition coefficient at a low concentration of the lower fatty acid. n CONSTITUTION: A mixed solvent of isophorone and 5W30wt%, based on the isophorone, trioctylphosphine oxide can be brought into contact with an aqueous solution containing preferably a 1W3C lower fatty acid, preferably formic acid, acetic acid or propionic acid, in a low concentration to extract and recover the lower fatty acid, e.g. the acetic acid, at a high partition coefficient by an ordinary means such as distillation, etc. n EFFECT: The solubility in the aqueous phase and the solubility of water in the mixed solvent are low, and the method is advantageous to the energy cost in purification and further to continuous extraction of an aqueous solution of the lower fatty acid in a low concentration such as a fermentation liquor, etc. the number of theoretical plates in extraction can be reduced when an extractor, e.g. mixer-settler type, is used. the construction cost can be saved. n COPYRIGHT: (C)1986,JPO&Japio |
