ABSTRACT:
A method for separating carboxylic acids from mixtures with non-acids by an extractive distillation method using a lactam with a 5- or 6-membered ring, preferably N-methyl-2-pyrrolidone, as an extractant to extract the acids from the mixture with non-acids, followed by separating the extracted acids from the extractant by rectification.
