    Abstract: This invention relates to additives for oleaginous fluids containing extreme pressure and antiwear agents and containing less than 15 GC area percent higher dialkyl polysulfides and to a process for their production comprising:a) forming a first reaction mass comprising olefin, a sulfur source, and a catalyst;b) heating the first reaction mass to a temperature and for a period of time which is sufficient to form a mixture of dialkyl disulfides, dialkyl trisulfides and higher dialkyl polysulfides;c) forming a second reaction mass comprising the mixture of dialkyl disulfides, dialkyl trisulfides and higher dialkyl polysulfides formed in step (b), an organo phosphorus compound, and optionally an amine;d) heating the second reaction mass to a temperature and for a period of time which are sufficient to convert at least a portion of the higher dialkyl polysulfides to dialkyl trisulfide; ande) recovering said mixed additive containing extreme pressure agents and antiwear agents, wherein said recovered mixed additive contains less than 15 GC area percent higher dialkyl polysulfides.

    Abstract: An antifriction alloy containing iron, molybdenum and sulphur, and having a low coefficient of friction, even in the dry state, is disclosed. The alloy contains 8.0-26.6% iron, 41.0-62.5% molybdenum and 23.3-40.5% sulphur. The alloy may comprise a matrix of Fe.sub.x Mo.sub.3+y S.sub.4, where x and y are less than 1. (e.g. FeMo.sub.4 S.sub.5) in which is dispersed FeMo.sub.2 S.sub.4 and/or the .epsilon. phase of the Fe/Mo/S equilibrium diagram. The alloy reacts with a material against which it rubs, to form the sulphide of that material on the rubbed surface. The alloy may be made by chemical reaction, fusion, vacuum deposition, or powder metallurgy. It can be used alone, or as a surface layer on, or inclusion in, another material, or it can be dispersed as a powder in a lubricant.
