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.

Abstract: Methylparaffins having limited methyl branching may be prepared by contacting at least one linear olefin with hydrogen in the presence of a dual-function supported catalyst comprising a solid acid component and a hydrogenation component under conditions sufficient to catalytically isomerize the at least one linear olefin into an intermediate product comprising one or more branched olefins, and hydrogenating the one or more branched olefins to form an isoparaffin product comprising one or more methylparaffins. Heat transfer fluids comprising such methylparaffins may be used in various thermal management systems, such as within various systems of electric vehicles, server farms, or other locales in need of efficient heat transfer.

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: This disclosure relates to methods for producing purified aromatic esters useful as plasticizers, to the purified aromatic esters, and to polymer compositions containing the purified esters. The purified aromatic esters can be produced by esterifying carboxylic acid with methyl or ethyl alcohol, separating the resulting methyl or ethyl esters from the carboxylic acid and any byproduct impurities, and then transesterifying the methyl or ethyl esters with C4 to C14 alcohol to produce the purified aromatic esters. Additionally, precipitation, filtration, and wash steps can be employed to purify the carboxylic acid, the methyl or ethyl alcohol, and/or the aromatic esters.

Abstract: Disclosed are novel processes for making cyclohexanone compositions, from a mixture comprising phenol, cyclohexanone, and cyclohexylbenzene. The process includes hydrogenation of a feed stream comprising phenol, cyclohexanone, and cyclohexylbenzene. The feed stream may be subjected to one or more pre-hydrogenation treatments, such as passing through one or more sorbents, addition of basic chemical agents, and/or addition of water, so as to improve catalyst activity, minimize undesired side reactions, and/or remove catalyst poisons from the feed stream. The feed stream may be provided to a hydrogenation reaction zone in the vapor phase, with periodic alterations to hydrogenation reaction conditions such that the feed is provided in mixed liquid and vapor phase in order to carry out liquid washing of a hydrogenation catalyst bed within the hydrogenation reaction zone.
