摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.

摘要:
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.
