Abstract
Novel fluid mixtures of specified hydrocarbons meeting an array of structural criteria are described. Linear hydrocarbons having terminal double bonds and internal segments of specified differing chain lengths separated by one or more carbon atom(s) each of which has a methylidene substituent make up one group of such compounds. Another group is alkenyl end-capped compounds of the first group. Third and fourth groups are products formed by hydrogenation of the first and second groups, respectively. The products, whether end-capped or not, and whether hydrogenated or not, have desirable lubricating properties such as suitably low pour points and/or low NOACK volatility and/or very high viscosity index and thus can be used as base oils or as components in formulating lubricants.
