Abstract: Methyl paraffins formed by hydrogenating one or more LAO dimers comprising a vinylidene moiety or a trisubstituted olefin moiety may have advantageous heat transfer properties, particularly when incorporated within an electric vehicle. For example, methyl paraffins produced upon hydrogenating LAO dimers formed from one or more C6-C12 LAOS, particularly in the presence of a Hf metallocene catalyst system, may contain 12-24 carbon atoms, and collectively have a flash point of about 130° C. or above, a pour point of about −42° C. or lower, a thermal conductivity at 80° C. of about 0.165 W/m·K or higher, and a Mouromtseff number ranging from about 17,000 to about 27,000 kg/(s2.2·m0.6·K) at 80° C. Heat transfer fluids comprising such methyl paraffins may be placed in contact with a heat-generating component, such as a battery and/or motor of an electric vehicle, or within a similar type of battery system, including immersive configurations for a battery.

Abstract: Branched paraffins formed as a hydrogenated reaction product of one or more linear alpha olefins (LAOs) oligomerized with a BF3 catalyst system and comprising at least about 90 wt. % branched paraffin dimers may have advantageous heat transfer properties. Heat transfer fluids comprising the branched paraffins may be placed in contact with a heat- generating component, such as those found in electric vehicles, battery systems, and other locations in need of thermal management. Branched paraffin dimers formed from one or more LAOs having about 8 to about 12 carbon atoms may collectively have a Mouromtseff Number ranging from about 10,000 to about 16,000 kg/(s2.2.m0.6.K) at 80° C., a thermal conductivity at 80° C. of about 0.125 W/m.K or higher, and a flash point of about 140° C. or higher.
