Abstract: A lubricating oil composition of improved rust-inhibitory capability contains a small amount of a sulfated alcohol having a molecular weight in the range of 500 to 5,000 which is prepared by reacting an aliphatic alcohol or a phenol with ethylene oxide or propylene oxide or mixtures thereof to form a polyoxyalkenylated alcohol which is treated with sodium hydride, potassium, sodium, sodium methoxide, potassium methoxide or potassium tert-butoxide and then is sulfated by treating with chlorosulfonic acid.

Abstract: A process for the preparation of N-hydrocarbyl- substituted primary amines in the form of N-hydrocarbyl formimidate ester by the alkylation of hydrocyanic acid. The process comprises contacting a nonconjugated olefin with hydrocyanic acid and hydrogen fluoride in the presence of an alcohol or mercaptan.

Abstract: Functional fluid lubricating oil compositions are provided which comprise (A) an oil of lubricating viscosity, and (B) an effective amount of each of the following: (1) an alkenyl succinimide, (2) a Group II metal salt of a dihydrocarbyl dithiophosphoric acid, (3) a frictional modifier, (4) a basic sulfurized alkaline earth metal alkyl phenate, and (5) a chlorinated olefin containing from about 15 to 50 carbon atoms, from 20 to 60% by weight chlorine, and having a boiling point of at least about 300.degree. F. Such lubricating compositions are useful as functional fluids in systems requiring fluid coupling, hydraulic fluid and/or lubrication of relatively moving parts. The lubricating compositions of the invention are particularly useful as the functional fluid in automatic transmissions, particularly in passenger automobiles.

Abstract: Novel compositions are prepared from the thermal decomposition product of azidoformate esters reacting with aliphatic hydrocarbon olefins to form aziridine carbamates, which are then reacted with a polyamine free of primary amino groups and having at least one secondary amino group. These compositions find use as detergents and dispersants in lubricating oils and fuels, and also as emulsifiers.

Abstract: A process is disclosed for preparing overbased carbonated sulfurized magnesium alkylphenates. In the process, magnesium methoxide is carbonated and then contacted with an alkylphenol to form a normal magnesium phenate. The normal magnesium phenate is sulfurized and then contacted with an additional amount of carbonated magnesium methoxide to form the overbased sulfurized magnesium phenate.
