Functional fluid containing a hydrolysis suppressor
专利摘要

A functional fluid is disclosed which comprises in a mixture a major portion of a base oil and a minor amount of a 2-(3,4-epoxycycloalkyl)-5-5'-spiro-(3,4-epoxy) cycloalkyl-m-dioxane. The fluid may also contain a minor amount of a viscosity index improver, a small amount of water and other additives. ......

  • 权利要求: What is claimed is:1. A functional fluid comprising an admixture of1. a major portion of a base oil which is an organic ester or amide of a phosphorous acid, or mixtures thereof, and2. a minor portion, from 0.01 to 8 weight percent of said fluid, of at least one 2-(3,4-epoxycycloalkyl)-5-5'-spiro-(3,4-epoxy)cycloalkyl-m-dioxane having from 15 to 45 carbon atoms.2. The functional fluid defined in claim 1 wherein said base oil is a phosphate ester having this formula: ##EQU2## wherein R.sub.1, R.sub.2, and R.sub.3 are alkyl or aryl groups or mixtures thereof having from 3 to 10 carbons.3. The functional fluid defined in claim 2 wherein said base oil is a mixture of 70-98 weight percent of a trialkyl phosphate ester having from 4 to 9 carbons in each alkyl group and the remainder of a triaryl phosphate ester having from 6 to 15 carbons in each aryl group.4. The functional fluid defined in claim 3 wherein said trialkyl phosphate is a tributyl phosphate.5. The functional fluid defined in claim 4 wherein said m-dioxane is 2-(3,4-epoxycyclohexyl)-5-5'-spiro-(3,4-epoxy) cyclohexane-m-dioxane.
