High quality synthetic lubricating oils are provided when certain olefinic monomers such as ethylene, propylene and a third 1-olefin are copolymerized and thereafter dewaxed by means of a urea adduction process.

Process for making synthetic lubricating oils

Lubricating oils containing certain hydroxyl-containing acid esters have been found to be effective friction modifiers and to aid in the reduction of fuel consumption in internal combustion engines.

Lubricant composition for reduction of fuel consumption in internal

A lubricant concentrate for use in metal processing comprises a sulfur compound such as a sulfurized olefin or sulfurized mineral oil and an ester prepared from a fatty acid having 12 to 40 carbon atoms or the dimer thereof or a polyalkenylsuccinic acid or anhydride and a hydroxyl-containing amine.

Metal working lubricant compositions

Polymer oils having reduced viscosity and increased viscosity index are produced by oligomerizing a mixture of short chain 1-olefins and long chain 1-olefins in the presence of water or alcohol promoted boron trifluoride catalyst and low-boiling recycle from a previous oligomerization run.

Process for improving olefin polymer oil properties

There is provided a method for depositing asphalt from an asphalt emulsion onto an aggregate, as in road construction. Prior to applying the asphalt emulsion, the aggregate is wetted down with water containing a minor amount of an anionic or a cationic coupling agent selected to have a charge opposite to that of the asphalt emulsion.

Controlled deposition of asphalt emulsions

An emulsifiable concentrate for use in metal processing, especially in can forming, comprises an ester prepared from a polyalkenylsuccinic acid or anhydride, and a hydroxyl-containing amine. It is critical to the invention with respect to can forming that the acid or anhydride contain, in addition to its basic carbon length, a chain derived from an olefin having from 16 to 28 carbon atoms.

Lubricant compositions for can forming

Synthetic hydrocarbon oils having excellent viscosity index and pour point combinations. They are made by a process involving the copolymerization of propylene or propylene plus higher 1-olefins with small amounts of ethylene.

Synthetic hydrocarbon lubricating oil

Synthetic esters or mixtures thereof, containing a free hydroxyl group in the molecule, are useful as lubricants for internal combustion engines, preferably in combination with synthetic hydrocarbon fluids. The composition, when used to lubricate an internal combustion engine, reduces the fuel consumed by such engine.

Synthetic ester and hydrogenated olefin oligomer lubricant and method of

Compounds having biocidal and antirust properties which constitute the reaction product of (a) a benzotriazole compound having the formula: ##STR1## wherein R is hydrogen or an alkyl group containing from about 1 to about 6 carbon atoms and (b) a water soluble base, characterized by a basicity greater than that of said benzotriazole compound, such as an alkali metal hydroxide or a hydrocarbyl amine. Lubricant compositions are also provided containing biocidal and antirust amounts of the aforenoted reaction product.

Lubricant compositions containing biocidal, antirust additives

Asphaltic compositions are provided comprising a major proportion of straight-run asphalt, and minor proportions of a refractory aromatic residual fraction (syntower bottoms), ethylene-vinyl acetate copolymer and terpenic resin.

Asphalt composition and its manufacture

Lubricant, particularly metal working, compositions which contain, in an amount sufficient to impart improved load carrying ability, sulfur and an organic hydroperoxide are provided.

Lubricant compositions containing organic hydroperoxides

Compositions containing a base lubricant, an antiwear amount of a polypropylene glycol and sulfur; and a solubility improving amount of a monohydric alcohol having from 5 to 30 carbon atoms are provided. These compositions are especially useful for metal working and cutting applications.

Metal working compositions

Lubricant compositions are provided containing from about 0.5 to about 65%, by weight, of an amine salt of a partial ester of an alkyl or alkenyl succinic acid. These amine salts are effective as biocidal and anti-rust agents.

Lubricant compositions

Improved asphalt compositions are provided which are produced by forming a homogeneous blend of marginal asphalt stock with coal-derived asphaltenes, and air-blowing the homogeneous blend to yield an asphalt composition having a viscosity-penetration index higher than about 2.5 .times. 10.sup.5.

Asphalt compositions

Lubricant compositions are provided comprising a substituted indan having the structure: ##SPC1## In which R is at least one member of the group consisting of hydrogen, alkyl, phenyl, carboxy alkyl, carboxy phenyl, phenoxy and their thiosubstituted derivatives. The method for the preparation of these substituted indans is also provided.
