摘要:
A quaternary ammonium salt detergent made from the reaction product of the reaction of: (a) a hydrocarbyl substituted acylating agent and a compound having an oxygen or nitrogen atom capable of condensing with said acylating agent and further having a tertiary amino group; and (b) a quaternizing agent suitable for converting the tertiary amino group to a quaternary nitrogen and the use of such quaternary ammonium salt detergents in a lubricating composition.
摘要:
A composition is disclosed which cleans baked-on, carbonized sludges and varnish deposits from the internal surfaces of automobile, motorcycle and truck engines. The product comprises a mutually synergistic solution of selected cyclic compounds, aliphatic amines and water, preferably dissolved in a hydrocarbon or hydrocarbon and aliphatic lower alcohol fuel base. The solution or base product may be placed in a pressure resistant (aerosol) dispenser, and pressurized. When injected into an engine over a period of time, significant removal of deposited contaminants occurs, resulting in smooth and efficient engine operation and lower levels of unburned hydrocarbon fuel, carbon monoxide, and other air pollutants.

摘要:
The present invention relates to functional fluid compositions containing friction modifiers, and specifically stable compositions containing friction modifiers with limited solubility in and/or limited compatibility with the functional fluids with which they are used. In particular the present invention deals with functional fluids used in internal combustion engines, such as engine oils, and friction modifiers derived from hydroxy-carboxylic acids, where the friction modifier is present in the functional fluid composition at levels that would otherwise cause the composition to be unstable and/or hazy.
摘要:
A method of protecting silver parts and inhibiting copper corrosion in an internal combustion engine and a silver-wear and copper-corrosion protection additive in a lubricating composition comprising a major proportion of an oil of lubricating viscosity and a minor amount of a silver-wear and copper-corrosion protection additive comprising the reaction product of an amine, formic acid, and a C.sub.5 to C.sub.60 carboxylic acid.
摘要:
Disclosed are selected alkylhydrazine and hydroxyalkylhydrazine adducts of diisocyanates having the formula ##STR1## wherein R.sub.1 is selected from the group consisting of an arylene group containing from 6 to about 12 carbon atoms and a cycloalkylene group containing from about 5 to about 20 carbon atoms; and wherein R.sub.2 is selected from the group consisting of alkyl group containing from 1 to about 20 carbon atoms and hydroxyalkyl group containing from 2 to about 20 carbon atoms. These compounds have utility as antioxidants for a variety of organic compounds subject to oxidative degradation, including functional fluids such as petroleum fuels and lubricants.
摘要:
Disclosed are selected poly(oxyalkylated) hydrazines of the formula: ##STR1## wherein R is selected from hydrogen, lower alkyl groups having from 1 to 4 carbon atoms, phenyl and mixtures thereof; and the sum of w, x, y, and z is from about 4 to about 20. These compounds are shown to be effective corrosion inhibitors for hydraulic fluids.
