New ashless TBN molecules are synthesized, and lubricant compositions containing them, boost the total base number. The lubricant compositions further tested for ASTM D6594 copper corrosion test meets ASTM limits.

Novel friction reducing additives provide friction modification at a lower effective concentration when added to a motor oil base. A friction reducing motor oil composition may include motor oil base and a friction reducing additive having the structure of the general formula (I): wherein: Ris a straight or branched C-Calkyl or alkenyl; Ris H, or a straight or branched alkyl of C-C; Ris H, or a straight or branched alkyl of C-C; P is 0 or C; n is C-C; and m is C-C.

Friction modifier for motor oil

A traction fluid comprising a blend of 2,3-dicyclohexyl-2,3-dimethylbutane (HAD) and 2,3-dicyclohexyl-2,3-dimethylbutane (iso-HAD) is found to have a lower viscosity at low temperatures when compared to a traction fluid having only HAD or only iso-HAD as a base fluid with no compromise to traction coefficient. The traction fluid may comprise additives. The traction fluid usually comprises HAD:isoHAD between about 8:1 to about 1:3. Further, the HAD:iso-HAD traction fluid blend is produced by a method of simultaneous co-production of hydrogenated HAD and hydrogenated iso-HAD from an alpha styrene dimer and an iso-HAD precursor with a yield of about 90% in a method that does not require a purification step.

Traction fluid with improved low temperature properties

A procedure for hydrogenation of alpha dimethyl styrene dimer that is scalable, economical, and safe is provided. These processes routinely provide greater than a 98% yield and require no purification step. The methods of producing hydrogenated alpha dimethyl styrene dimer comprising adding to a reactor under nitrogen a catalyst comprising Ru/C or Rh/C and an alpha dimethyl styrene dimer to form a catalyst and alpha dimethyl styrene dimer reaction mixture. The reaction mixture is then heated under pressure until hydrogenation of the alpha dimethyl styrene dimer is complete. To recover the hydrogenated alpha dimethyl styrene dimer, the reaction mixture is filtered through a celite bed under nitrogen.
