    Abstract: A process is described for the separation and recovery of isocyanate monomers from isocyanate concentrates which leaves a residue which is liquid and burnable. The process for the separation and recovery of isocyanate monomers from isocyanate concentrates formed in the production of isocyanates and comprising a volatile isocyanate monomer and by-products comprises the steps of: (A) preparing a mixture comprising (A-1) the isocyanate concentrate; and (A-2) an oil solution comprising; (A-2-a) a major amount of hydrocarbon oil, and (A-2-b) a minor amount of at least one ashless dispersant; and (B) heating the mixture to an elevated temperature at reduced pressure whereby isocyanate monomer is distilled and recovered leaving a liquid residue. The presence of the oil solution in the mixture facilitates the distillation of the isocyanate concentrate, generally improves the yield of distilled isocyanate monomer, results in a residue which is liquid and easily removed from the distillation apparatus, and the liquid residue can generally be burned without difficulty.

    Abstract: Sulfur-containing, oil-soluble compositions are described which are useful as lubricating oil additives, particularly in lubricants containing little or no phosphorus. In one embodiment, the compositions of the invention comprise (A) at least one metal salt of at least one dithiocarbamic acid of the formula R1(R2)N-CSSH (I) wherein R1 and R2 are each independently hydrocarbyl groups in which the total number of carbon atoms in R1 and R2 is sufficient to render the metal salt oil-soluble, (B) at least one oil-soluble sulfurized organic compound, and (C) at least one auxiliary corrosion-inhibitor. In other embodiments, the compositions also contain (D) at least one detergent/dispersant. Lubricating oil compositions containing the compositions of the invention exhibit improved oxidation-corrosion-inhibiting properties, anti-wear properties, and/or extreme pressure properties. Such lubricating compositions containing less than about 0.1% by weight of phosphorus also exhibit good compatability with nitrile seals.
