Engine deposits are controlled by dispensing an additive to fuel. In one aspect, the additive comprises paraffins. In another aspect, a solid form additive for dispensing fuel additive to fuel in solid form is provided by employing a structural agent which is soluble and dispersible in fuel to contain and provide dimensional stability to the additive.

Solid form additives and method of forming same

Method of forming solid form fuel additives

A lubricating grease is formed by overbasing a mixture comprising lubricating oil, an alkaline earth metal petroleum sulfonate, and a lower molecular weight sulfonic acid derivative. The lubricating grease formed is highly basic and has a high drop point.

Process of preparing grease composition

Grease composition and preparation thereof

A lubricating composition comprising a hydrogenated oligomer of a 1,3-diolefin, e.g., 1,3-butadiene, and a calcium petroleum sulfonate which can be at least one of a substantially neutral calcium petroleum sulfonate and an overbased calcium petroleum sulfonate is disclosed. The incorporation of the calcium petroleum sulfonate yields a composition having an unexpectedly, considerably lower pour point than that possessed by the hydrogenated oligomer alone.

Lubricating composition comprising hydrogenated oligomers of

A molten polymer is extruded through at least one orifice to produce a filament which is immediately cooled to a temperature below its glass transition temperature by contacting the filament with a gas having a temperature ranging from about +10.degree. C. to about -20.degree. C.

Method for producing filaments of high tenacity

A calcium petroleum sulfonate containing lubricating oil is overbased using lime, carbon dioxide, a low boiling alcohol and a monoalkylbenzene solvent. In one embodiment a propane-fractionated lubricating oil, calcium petroleum sulfonate, toluene, methanol and hydrated lime are treated with carbon dioxide at a temperature of about 60.degree. C. for about 20 minutes. A resulting overbased calcium petroleum sulfonate obtained exhibited a base number of 315.

Overbasing calcium petroleum sulfonates in lubricating oils employing

The heavy reaction product obtained upon separation, as by distillation, of light reaction products of branched aliphatic dinitriles is useful as rust inhibitor in lubricating oils and greases.

Residue of hydrogenation product of branched aliphatic dinitriles as

Fabrics produced from aromatic sulfide polymers are rendered water-repellent by heat treatment near, but below, the melting point of the polymer for a finite period of time. The resulting heat-treated fabric is suitable for flame retardant tents, waterproof clothing, filters, etc.
