ABSTRACT:
Deposit formation in distillation units, particularly column reboiler units, associated with the separation and purification of dialkyl phosphorochloridothioates from a crude material containing oxygenated compound impurities, is inhibited by incorporating in the feed stock a minor proportion (generally about 0.05 to about 15.0 weight percent) of an acylated amine prepared by reacting a hydrocarbon-substituted succinic compound with an alkylene amine or a hydroxyalkyl-substituted alkylene amine.
