Abstract:
Reaction product formed by the condensation of alkanolamine, polyhalopolyhydropolycyclicdicarboxylic acid or derivative and aliphatic substituted dicarboxylic acid. The reaction product has utility as a stabilizer against deterioration of organic substances, such as lubricants, hydrocarbon oils and plastics, as well as utility as a detergent, dispersant, extreme pressure additive, flame retardant and also possessing insecticidal properties.
Abstract:
A lubricating compound for use in extreme pressure environments comprising, in one embodiment, a major amount of a base lubricating agent and a minor amount, but at least about 1 percent by weight, of a fish oil-based lead soap. The base lubricating agent includes calcium complex grease, barium grease, aluminum grease, sodium grease and lithium grease. The fish oil in the lead soap includes tuna oil, herring oil, menhaden oil and sardine oil.
Abstract:
A lubricating and sealing compound for sealing pipe threads and the like comprising: (1) 4 percent to 92.5 percent by weight of a base lubricating agent and, preferably, of a base grease produced using a soap from the group of aluminum, barium, calcium complex, lithium and sodium soaps; (2) 2 to 20 by weight of a fish oilbased lead soap; (3) 0.5 to 10 percent by weight of a sulfur modified sperm oil such as sulfurized or sulfonated sperm oil; and (4) 5 to 90 percent by weight of solids. The solids comprise either copper alone or, preferably, copper in combination with; (5) 5 to 30 percent by weight of this compound of powdered lead; and (6) 5 to 30 percent weight of amorphous graphite.
Abstract:
Lubricating compositions useful for lubricating high-temperature alloys are prepared by adding organosilicon compounds containing silicon-bonded ethyl groups substituted with iodine, with bromine or chlorine, and with alkoxy, acyloxy or hydroxy groups to oils of lubricating viscosity. The organosilicon compounds are prepared by adding I2 and Br2, I2 and Cl2, IBr, or ICl to vinylsubstituted silanes and siloxanes in the presence of alcohols or carboxylic acids or with subsequent water treatment.
Abstract:
The invention relates to synthetic lubricants used at very high temperatures in the process of continuous casting of molten metals. The lubricants are applied as a liquid film to the surfaces of the molds into which the metal is poured. In continuous casting of steel the molten steel is poured into an open-bottomed mold of the desired product shape. The steel is cooled in the mold just enough to harden the exterior surface of the casting, which forms a shell or container that holds the balance of the liquid metal. The inner walls of the mold are continuously coated with a liquid lubricant as the metal is poured therein. The partially solidified casting is then continuously withdrawn from the bottom of the mold, where it is further cooled by water sprays until all the metal is solidified. The casting is cut as it descends through the equipment into desired lengths. The polyol esters of fatty acids having 12 to 22 carbon atoms, or mixtures thereof, are excellent lubricants for molds used in continuous casting of metals. The preferred polyols have two to 12 hydroxy groups and at least five carbon atoms, including for example, pentaerythritol or polymers thereof, trimethylol ethane, trimethylol propane, and glycols containing from two to 40 carbon atoms. Also included in these polyols are inositol, mannitol, sorbitol, glucose, sucrose, trimethylol benzene, hexamethylol benzene, methyl glucosides, polyglycerols and, in fact, any polyol capable of reacting with at least two selected fatty acid molecules to form a minimum of a diester.
Abstract:
GREASES SUBSTANTIALLY RESISTANT TO OIL SEPARATION AT ELEVATED TEMPERATURE ARE FORMED BY PREPARING A GREASE COMPOSITION CONTAINING A COMPLEX SOAP OR A CLAY GELLING AGENT AND THEN MIXING WITH THE GREASE A MINOR AMOUNT OF A POLYISOBUTLYLENE, A POLYSTYRENE, OR A METHACRYLATE COPOLYMER, WITHOUT SUBSTANTIAL SHEARING OF THE POLYMER.
Abstract:
ORGANOSILICON COMPOUNDS CONTAINING SILICON-BONDED ETHYL GROUPS SUBSTITUTED WITH IODINE, WITH BROMINE OR CHLORINE, AND WITH ALKOXY, ACYLOXY, OR HYDROXY GROUPS HAVE BEEN PREPARED BY ADDING I2 AND BR2, I2 AND CL2, IBR, OR ICI TO VINYL-SUBSTITUTED SILANES AND SILOXANES IN THE PRESENCE OF ALCOHOLS OR CARBOXYLIC ACIDS OR WITH SUBSEQUENT WATER TREATMENT. LUBRICATING COMPOSITIONS USEFUL FOR LUBRICATING HIGH TEMPERATURE ALLOYS ARE PREPARED BY ADDING SUCH SUBSTITUTED ORGANOSILICON COMPOUNDS TO OILS OF LUBRICATING VISCOSITY.
