    Abstract: Mineral lubricating oil compositions containing oil-soluble overbased alkaline earth metal hydrocarbon sulfonates, employed in internal combustion engines, are improved as to their antirust, sludge inhibiting and/or antiwear properties by incorporating into such compositions, in colloidal form, small amounts, for example 0.01 to 10.0 wt. percent, of the total oil composition, of in situ formed oil-insoluble inorganic alkaline earth metal phosphorus salts derived from the lower oxy or thio acids of phosphorus or from the corresponding oxides or sulfides of phosphorus which, upon hydrolysis, yield the lower oxy or thio acids of phosphorus. The preferred process of preparing such compositions involves the treatment of the neutral or overbased alkaline earth metal sulfonates, either of petroleum origin or of synthetic long chain alkaryl origin, or mineral oil concentrates thereof, and which have been in the past, conventionally employed as oil additives, with up to the stoichiometric amount of the phosphorus acid, thio acid, oxide or sulfide required to at least partially neutralize the free alkalinity of the overbased sulfonate, filtering therefrom any precipitate formed as a result of such treatment of the sulfonate or oil concentrate thereof, and recovering an oil-soluble alkaline earth metal sulfonate product, or oil concentrate thereof, containing colloidal oilinsoluble alkaline earth metal phosphorus compounds of reducing nature formed in situ.

    Abstract: A PROCESS FOR SEPARATING A MIXTURE CONTAINING LIQUID ORGANIC COMPOUNDS, HAVING DIFFERENT INTERFACIAL TENSIONS WHEN MEASURED AGAINST SUBSTANTIALLY HYDROCARBON-INSOLUBLE POLAR LIQUIDS, INTO ITS COMPONENT PARTS COMPRISES THE STEPS OF COMBINING SAID MIXTURE OF ORGANIC LIQUIDS WITH SURFACTANTS AND WITH A POLAR LIQUID SUBSTANTIALLY IMMISCIBLE WITH ANY OF THE COMPONENTS OF THE MIXTURE BEING SEPARATED THEREBY SELECTIVELY FORMING TWO PHASES, ONE BEING A MICROEMULSION RICH IN THE ORGANIC COMPONENTS HAVING THE LOWER INTERFACIAL TENSION, WHWREIN SAID POLAR LIQUID IS THE CONTINUOUS PHASE, AND THE OTHER BEING AN OIL PHASE RICH IN THE COMPONENTS HAVING THE HIGHER INTERFACIAL TENSION WITH RESPECT TO THE POLAR LIQUID. THE TWO PHASES ARE THEN SEPARATED.
