A new class of monoepoxyethylenecyclohexyl compounds useful as acid scavengers and corrosion inhibitors in functional fluid compositions.

Novel monoepoxy compounds as acid scavengers in functional fluids

Functional fluid compositions comprising a major amount of a base stock material which is an ester or amide of an acid phosphorus, a di- or tricarboxylic acid ester, an ester of a polyhydric compound or mixtures thereof, optionally minor amounts of other base stock materials or base stock modifiers such as viscosity index improvers, cavitation damage inhibitors, and lubricity agents, and an additive amount of an acid scavenger and corrosion inhibitor which is a monoepoxy substituted cyclohexane such as C.sub.1-4 alkyl-3,4-epoxycyclohexane. The compositions are particularly useful as aircraft hydraulic fluids.

Functional fluid compositions containing epoxide stabilizers

Certain phenyl hydrazides of N-phosphonomethylglycine have been found to be useful as herbicides and plant growth regulators.

N-phosphonomethylglycine phenyl hydrazides

Chemical compounds

Functional fluid compositions comprising a major amount of a base stock material which is an ester or amide of an acid phosphorus, a di- or tricarboxylic acid ester, an ester of a polyhydric compound or mixtures thereof, optionally minor amounts of other base stock materials or base stock modifiers such as viscosity index improvers, cavitation damage inhibitors, and lubricity agents, and an additive amount of an acid scavenger and corrosion inhibitor which is a monoepoxy norbornyl carboxylate such as C.sub.1.sub.-4 alkyl-5,6-epoxynorbornane carboxylate. The compositions are particularly useful as aircraft hydraulic fluids.
