Abstract: An additive for lubricants including a dispersible metal complex compound containing phosphorus and nitrogen. This complex compound consists of a co-ordination compound containing a fatty acid residue and at most one RCOO group per two metal atoms. Zinc is the metal of preference. Utilization for wet drawing of metal wire.
Abstract: There is disclosed a lubricant additive ingredient that imparts extreme pressure anti-wear properties to lubricant additive compositions. Specifically, there is disclosed a derivative of a vegetable oil triglyceride, a wax ester or a telomerized oil reacted with phosphorous pentasulfide to produce a phosphorous-sulfur (PS) extreme pressure additive.
