C. to about 200.degree. C. for a period of about four hours;(c) bubbling CO.sub.2 into said agitated mixture to provide an intermediate product; and(d) filtering said intermediate product at a rate of about 50 ml per 3 to 6 minutes to provide the lubricant detergent additive.

    Abstract: A lubricant concentrate is provided for forming stable, translucent oil-in-water emulsions upon dilution with a major part of water. The concentrate comprises a suitable base oil blended with polyisobutylene and an emulsifier/dispersant and antiwear/antirust inhibitor system. Typical emulsifier/dispersants include the metal soaps of rosin acids, the alkylene oxide condensation products of a fatty amine or the reaction product thereof with a polyalkenylsuccinic acid or anhydride. Zinc dialkyldithiophosphates and metal dialkylnaphthalene sulfonates are useful antiwear and antirust inhibitors.

    Abstract: A method of preparing superbased magnesium sulfonates by dispersing MgO in the preformed low viscosity overbased magnesium sulfonates. The low viscosity overbased magnesium sulfonates is prepared by sulfonating an alkyl benzene with a material containing SO.sub.3, preferably oleum, and reacting the alkyl benzene sulfonate with magnesium oxide in the presence of a low viscosity diluent, such as No. 2 oil or LOPS (low odor paraffin solvent), together with water, alcohol, and CO.sub.2. The newness of the method lies in the steps of preferably positively utilizing oleum which contains a minor amount of sulfuric acid as a promoter and utilizing also a surfactant couple of a C.sub.12 -C.sub.18 fatty acid such as oleic acid and an ethanol amide such as a lauryl diethanol amide, which may be Witcamide 5138; where a ready made sulfonate is used, such as SA697 (Conoco), H.sub.2 SO.sub.4 is utilized. In certain instances the amide may be omitted with satisfactory results occurring by using the acid alone.Of particular interest is the preparation of a concentrated magnesium sulfonate wherein the water and alcohol are removed by distillation and a diluent such as LOPS or No. 2 oil is added to produce a slurry.An important feature of this process lies in the reduction in size of the magnesium oxide particles. CO.sub.2 is preferentially bubbled through the mixture after introduction of the magnesium oxide and at a temperature range of 30.degree.-80.degree. C. with stirring. A typical zone of particle size is 40-50% of about 200 A and 50-60% of 0.1-1.0 microns. This is quite advantageous where an emulsion is formulated and the percentage of magnesium is in the area of 14-23% and preferably 20% or over.

    Abstract: Mineral oil or synthetic hydrocarbon base hydraulic fluids containing a zinc bis(dialkyldithiophosphate) as an antiwear agent are stabilized against degradation at elevated operating temperatures by the incorporation in the hydraulic fluid of an appropriate Group I or Group II metal dialkylnaphthalene sulfonate. For example, a hydraulic fluid containing a zinc bis(dialkyldithiophosphate) is stabilized by the presence of a minor amount of zinc dinonylnaphthalene sulfonate.
