Patent

CA 1333593

Lubricant additives are produced by reacting an alkoxylated amine, preferably a di- alkoxy long chain alkyl amine, such as a propoxylated amine, with a disubstituted organic phosphite, preferably a dialkyl (C8 - C30) phosphite. The additives preferably also contain a boron moiety which is reacted with the phosphite and amine, preferably simultaneously in a one step reaction. The additives are particularly useful in metalworking oils and particularly as extreme pressure additives to replace the currently used chlorinated paraffin additives.
