Abstract
Lubricant additives are producd by reacting an alkoxplated amine with phosphorous acid. The additives preferably also contain a boron moiety which is reacted with the phosphorous acid and amine, preferably in a one step reaction. More preferably, a mono-functional alcohol or a long-chain aliphatic carboxylic acid is added to this mixture. The additives are particularly useful in metalworking oils and particularly as extreme pressure additives to replace the currently used chlorinated paraffin additives.
