| titleOfInvention | Process of separating nitrile-hydrocarbon mixtures |
| abstract | Nitriles are separated from mixtures with hydrocarbons such as are obtained by cracking nitriles of high molecular weight such as stearonitrile, as described in Specifications 467,043 and 467,044 by treating the mixture with aqueous alcohols, aqueous phenols, amines, or water-soluble carboxylic acids so as to form two phases, and treating the extract phase, containing the nitrile and solvent, so as to diminish the solubility of the nitrile which then forms a separate layer. The alcohols mentioned include methyl, amyl, cyclohexyl, and allyl alcohols, and the initial extraction may be effected in several stages. The extract when using an alcohol as solvent is treated with water or in the case of a phenol with dilute soda solution. The acids mentioned include acetic, acrylic, valeric, and caproic acids; the extract is treated with water to separate the nitriles. The amines mentioned include aniline, ethylamine, diethylamine, allylamine, diallylamine, benzylamine, pyridine, and cyclohexylamine; the extract is treated with a dilute acid such as hydrochloric acid to separate the amine. |
