Abstract
1,167,793. Acrylic, methacrylic acids. BADISCHE ANILIN- & SODA-FABRIK A.G. 17 Feb., 1967 [19 Feb., 1966], No. 7688/67. Heading C2C. Acrylic and/or methacrylic acid is/are separated from mixtures containing them by extraction with a 4- to 7-membered lactam with a hydrocarbon (6-20 C) radical as a substituent on the nitrogen atom. Propiolactams, pyrrolidones, piperidones and caprolactam with an alkyl, alkenyl, cycloalkyl, aryl or aralkyl radicals as substituents are used, e.g. N-isooctylpyrrolidone, N-dodecylpyrrolidone, and N- oleylpyrrolidone. The extraction may be bathwise or continuously in one or more stages, and may be liquid-liquid extraction or extraction from the gas phase.
