Abstract

Molybdenum-containing compositions are prepared by the reaction of an acid of molybdenum or salt thereof, phenol or aldehyde condensation product therewith, and a primary or secondary amine. The preferred amines are diamines such as tallow-substituted trimethylene diamine and their formaldehyde condensation products. An optional but preferred ingredient in the reaction mixture is at least one oil-soluble dispersant. The molybdenum-containing compositions are useful as additives in lubricants and fuels, and are especially useful in lubricants when combined with compounds containing active sulfur.
