ABSTRACT:
When different trialkyl methanes containing 25 through 36 carbon atoms are mixed the mixture exhibits surprisingly superior lubricant properties including low viscosity, high VI, low volatility, very low pour point and a dynamic viscosity at low temperatures that is less than those of PAO lubricants. Statistically predictable mixture compositions of mixed trialkyl methanes are prepared by reaction of mixtures of n-alkyl organometallic compounds with mixed aliphatic esters or equivalent compounds.
