MPD 221 CANADA S P E C I F I C A T I O N MANUFACTURE OF IMIDAZOLINE COMPOUNDS A B S T R A C T The invention provides a process for reducing the diamide content of imi- dazoline having the formula:- Image wherein R represents an aliphatic group having at least 4 carbon atoms and R1 represents an alkyl or alkenyl group having from 1 to 4 carbon atoms. The mixture of imidazoline and diamide is reacted with a primary or secondary amine which deacylates the diamide to an amido-amine. The product of this deacylation is an imidazoline solution which remains clear even on prolonged storage. The imidazoline is produced by reaction of an acid RCOOH with a diamineNH2(CH2)2NHR1. Preferably this diamine is used as the deacylating agent.
