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 C-CLAOS, 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/(s·m·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.
