| titleOfInvention | Method for isolating acids from chemical reaction mixtures by using 1-alkylimidazoles |
| abstract | The invention relates to a method for isolating acids from chemical reaction mixtures by means of an auxiliary base, whereby this auxiliary base: b) forms a salt with the acid, which is liquid at temperatures at which the valuable product is not significantly decomposed during the isolation of the liquid salt, and; c) the salt of the auxiliary base, together with the valuable product or with the solution of the valuable product, forms, in a suitable solvent, two non-mixable liquid phases. According to the invention, an alkyl imidazole is used as the auxiliary base and has a solubility, in 30 % by weight of sodium chloride solution at 25 DEG C, of 10 % by weight or less and whose hydrochloride has a melting point of less then 55 DEG C. |
