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。
