Abstract

127,740. Rintoul, W., Thomas, J., and Nobel's Explosives Co. June 15, 1918. Amines.-Tertiary amines are separated from admixed primary or secondary amines by treating the mixture with ethylchlorformate to convert the primary or secondary amines into urethanes; the unattacked tertiary base is removed from the product by washing with dilute acid, and recovered from the acid solution by treatment with alkali; the separated urethane is hydrolyzed to give the primary or secondary amine. An example is given of the treatment of crude dimethylaniline containing monomethylaniline.
