  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.

  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.

  发现一种牵引液，由2,3-二环己基-2,3-二甲基丁烷（HAD）和2,3-二异环己基-2,3-二甲基丁烷（iso-HAD）混合而成，与仅含有HAD或仅含有iso-HAD作为基础流体的牵引液相比，在低温下具有较低的粘度，而不会影响牵引系数。牵引液可以包含添加剂。牵引液通常包含HAD：isoHAD在8:1至1:3之间。此外，HAD：iso-HAD牵引液混合物是通过同时共生产氢化HAD和氢化iso-HAD的方法从α-苯乙烯二聚体和iso-HAD前体中获得的，该方法的收率约为90％，不需要纯化步骤。
