ABSTRACT:
A method for preventing a flushing oil used in recirculating toilets from turning yellow and having an offensive odor when contacted with animal waste products containing, among other things, water, carotene, bilirubin, oil soluble unsaturated fats, ammonia, amines and amides such as urea which includes the steps of mixing with said waste products a water-soluble compound having an active chlorine atom whereby said water-soluble chlorine compound is dissolved in the water contained in said waste products and reacts with the ammonia, amines and/or amides to form an oil soluble N-chloro-amine or amine (particularly NCl.sub.3) which is the reaction product of said ammonia, amide or amine contained in said waste product and the chloro containing compound, said chloro-amide or amine being soluble in said flushing oil, and contacting said flushing oil with said N-chloro-amide or amine thereby dissolving said chloro-amide or amine in said flushing oil to contact said oil soluble unsaturated fats, carotene and bilirubin and preventing said oil from turning yellow.
