Lubricant additives are produced by reacting an alkoxylated 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.
润滑油添加剂是通过烷氧基化胺与
磷酸反应制得的。添加剂最好还含有一个
硼基,该
硼基与
磷酸和胺反应,最好是一步反应。更优选的是,在该混合物中加入单官能醇或长链脂肪族
羧酸。这种添加剂在
金属加工油中特别有用,尤其是作为极压添加剂,可以取代目前使用的
氯化石蜡添加剂。
