Synthetic isoparaffinic premium heavy lubricant base stock |
摘要 |
A synthetic, isoparaffinic heavy hydrocarbon composition useful as a heavy lubricant base stock contains hydrocarbon molecules having consecutive numbers of carbon atoms, is a liquid at 100° C., at which temperature its kinematic viscosity is above 8 cSt and has respective initial and end boiling points of at least 850 and 1000° F. (454 and 538° C.). The branching index BI and the branching proximity CH2>4 of the isoparaffinic hydrocarbon molecules, are such that:as measured over the hydrocarbon composition as a whole.
