A sulfurized alkaline earth metal (e.g., calcium) dodecylphenate is prepared by reacting (i) dodecylphenol with (ii) calcium hydroxide or calcium oxide in an amount of about 0.3 to about 0.7 moles per mole of dodecylphenol charged and (iii) an alkylene glycol in an amount of about 0.13 to about 0.6 moles per mole of dodecylphenol charged; and reacting the product of the first step with sulfur in an amount of about 1.6 to about 3 moles per mole of dodecylphenol charged; and thereafter optionally reacting the product with additional calcium hydroxide or calcium oxide and with carbon dioxide so as to form an overbased phenate. The product thus prepared has reduced levels of monomeric dodecylphenol.

A coupler is described for use in carbon black filled rubber compositions. The coupler includes an amine group and a thiol group or a polysulfidic linkage. The coupler improves the interaction of the carbon black with the rubber as measured by a decrease in the tan delta at 60&deg; C. while substantially maintaining the tan delta at 0&deg; C.

Continuously variable transmissions are lubricated by supplying to the transmission a composition of an oil of lubricating viscosity and an oil-soluble zinc salt containing at least one hydrocarbyl group of at least 4 carbon atoms. The amount of the zinc salt is sufficient to provide an increased steel-on-steel dynamic coefficient of friction for the composition, being at least 0.125. The composition is substantially free from thiophosphate salts and exhibits a copper corrosion rating of 1B or better (ASTM-130).

The present invention is directed to a composition that contains polysulfides and that has a reduced odor level and to a method for reducing the odor of polysulfides. The composition contains a polysulfide and an inhibitor that reduces the odor level. The polysulfides include sulfurized olefins prepared by reacting the olefin with sulfur and H S in the presence of a catalyst. The inhibitors are selected from the group consisting of hydrocarbyl acrylates and hydrocarbyl methacrylates. The method for reducing the odor level of polysulfides involves contacting the polysulfide with an inhibitor selected from the group consisting of hydrocarbyl acrylates and hydrocarbyl methacrylates under conditions that reduce the odor level.

Various novel urazole compositions have been discovered that may be generally represented by the formula: ##STR1## wherein T and Q may be the same or different and represent hydrogen, hydrocarbyl, sulfur, phosphorus, boron, a metal cation, acyloxy hydrocarbyl, imido hydrocarbyl, hydrocarbyl repeating units, hydrocarbyl urazole (I) containing repeating units, an acyl urazole repeating units, an acyl group, or hydrocarbyl acyl containing group, a repeating unit of an acyl group, a repeating unit of a hydrocarbyl acyl containing group, or together form a pi bond between the two nitrogen atoms and A is hydrogen, hydrocarbyl, a hydrocarbyl urazole I group, a repeating unit of a hydrocarbyl containing acyl group or a repeating unit of a hydrocarbyl containing acyl group which is bonded directly to or through a hydrocarbyl group to another urazole (I) group. These compositions may be formulated with functional fluids for use in motorized vehicles.

A process for producing a sulfurized olefin product substantially free of ash containing waste is disclosed. The process involves dehydrohalogenation of an olefin/sulfur halide complex by contacting the complex with a protic solvent in the absence of any metal ion. The process allows for the solvolytic dehydrohalogenation of the complex. The sulfurized olefin product obtained is isolated and may be subjected to further processing to remove any remaining halides. The resulting sulfurized olefin is a useful additive in lubricating oils.
