Abstract: Salts of the anion of di-, tri- or tetrathiophosphoric acid of the formula I in which Z1 and Z2 are each independently an oxygen or sulfur atom, and Ra and Rb are each independently an organic group having 1 to 20 carbon atoms, and a cation which comprises a heterocyclic ring system having one to three nitrogen atoms.

Abstract: A turbine lubricant consisting of (A) alkylated diphenylamine and/or phenylnaphthylamines, and (B) sulfurized olefins and/or sulfurized fatty acids and/or ashless dithiocarbamates and/or tetraalkylthiuram disulfides, with the balance containing (C) base oils characterized by very low sulfur contents (<0.03 wt %) and a high level of saturates (>90 volume %), and optionally (D) neutral rust inhibitors, show superior oxidative stability and provide adequate corrosion protection and sludge control for turbine oil and R&O oil applications.

Abstract: Oil-based functional fluid compositions formulated for use as automatic transmission fluid, fluid for a wet brake system, or a friction-depending lubricant are improved by including in the composition a minor amount of at least one alcohol or polyol having less than 12 carbon atoms in the molecule. This results in a desirable increase in the dynamic and/or static coefficients of friction of automatic transmission or other frictional surfaces contacted by the composition. Preferred for this use is a composition formed by heating at least one ashless dispersant containing basic nitrogen and/or at least one hydroxyl group with a combination of at least (i) an inorganic acid of phosphorus, (ii) a boron compound, and (iii) a polyol having less than 12 carbon atoms, so that a liquid composition is formed. The boron compound and the inorganic phosphorus acid are preferably co-present during the heating.
