    Abstract: Sulfur-containing compositions are described which are prepared by sulfurizing (A) at least one fatty acid ester of a polyhydric alcohol, or (B) at least one fatty acid, fatty acid ester of a monohydric alcohol, or a mixture thereof, or (C) at least one other olefin, or (D) mixtures of any two or more of (A), (B) and (C), in the presence of a catalytic amount of (E) at least one salt of at least one dithiocarbamic acid of the formula R1(R2)N-CSSH wherein R1 and R2 are each independently hydrocarbyl groups, or (F) at least one mercapto benzothiazole, or (G) mixtures of (E) and (F). Preferably, various mixtures of (A), (B) and (C) are sulfurized in accordance with the invention. The incorporation of a catalytic amount of salt of at least one dithiocarbamic acid of Formula I or at least one mercapto benzothiazole (or mixtures thereof) results in the preparation of sulfurized compositions which are characterized by excellent oil solubility and higher sulfur contents, and the compositions generally are lighter in color when compared to sulfurized compositions prepared in the absence of such catalysts. The sulfurized compositions prepared in accordance with the present invention are useful as general purpose antioxidants and friction modifiers for lubricating compositions and automatic transmission fluids and in particular, as additives in metal working lubricants. The above-described sulfurized compositions as well as sulfurized compositions prepared in the absence of catalysts (E) and/or (F) are useful in asphalt compositions.
