ABSTRACT:
Hydrocarbyl substituted cyclopentadienes, cyclopentenes, and cyclopentanes are synthetic lubricating compositions. The preferred structures contain 1 to 6 alkyl groups which have 4 to 36 carbon atoms and may have different and varying carbon chain structures. The cyclopentenes and cyclopentanes are prepared by hydrogenation from the corresponding cyclopentadiene intermediates. The cyclopentadienes are prepared by reaction with hydrocarylating agents or alcohols. Mixtures are also disclosed.
