Abstract
Novel organoammonium compounds are provided, which are useful as additives for improving the antiwear and friction-reducing properties of lubricating compositions. The compound is formed by reacting a metal acid hydrate with one or more alkyl amines. Particular examples are the preparation of ditridecylammonium tungstate, di-n-octylammonium tungstate and ditridecylammonium molybdate.
