摘要:
Organic material is stabilized by addition of a sulfurized product made by heating a mixture of (a) sulfur and (b) a reaction product formed by reacting in the presence of an alkali metal hydroxide catalyst (i) a mixture of at least two different alkylphenols, each having an unsubstituted ortho and/or para position, and (ii) formaldehyde. Preferably, the reaction product is formed in the presence of a small amount of primary lower alkanol such as methanol. When added to lubricating oil the sulfurized products also impart wear and corrosion inhibiting properties.

WHEREIN: X is the same or different element selected from nitrogen or oxygen; Y is the same or different element selected from oxygen, sulfur or nitrogen and nitrogen when both X''s are oxygen; R is a hydrocarbylene or dihydrocarbylene having from 2 to 18 carbon atoms; R1 is the same of different hydrogen or a hydrocarbyl having from 1 to 24 carbons; R2 is the same or different R1 or a hydrocarbylene having from 2 to 18 carbon atoms with one end of each R2 bonding to the other R2 or to said R dihydrocarbylene; N IS 1 WHEN Y is oxygen or sulfur and 2 when Y is nitrogen; and M IS N-1.
Novel bisphosphoramides are prepared by reacting phosphorus oxychloride with a difunctional compound and a monofunctional compound within a liquid phase reaction medium to produce compounds having the structure:
摘要:
Triphenyl phosphates in which an average of at least one phenyl group per molecule is substituted with at least one alkyl group containing from 6-30 carbon atoms have been found to be excellent lubricants and functional fluids having much lower pour points and higher viscosity indices than conventional phosphate esters. These triphenyl phosphates are exceptionally useful as wear inhibitors in synthetic ester lubricants.
摘要:
A lubricating oil composition having good antiwear and load carrying properties comprises a lubricating oil and a mixture of (a) a quaternary hydrocarbyl ammonium salt of a mono (C1 C4) alkyl dihydrogen phosphate and (b) a quaternary hydrocarbyl ammonium salt of a di-(C1 - C4) alkyl hydrogen phosphate, e.g. tetrabutyl ammonium salts of mixtures of methyl hydrogen phosphate and dimethyl hydrogen phosphate.
摘要:
Lubricating compositions comprising polyphenyl thioethers, polyphenyl ethers-thioethers or mixtures thereof and containing small amounts of a polar organic compound and an organic phosphinic acid or ester have improved lubricating properties. These compositions are useful as lubricants over wide temperature ranges.
摘要:
N-hydroxyalkyl-N''-hydrocarbyl-hexahydropyridazines or Nalkoxyalkyl-N''-hydrocarbyl-hexahydropyridazines in which the hydrocarbyl is sec-alkyl or cycloalkyl. The novel compounds possess utility as additives to retard deterioration of organic substances due to weathering, oxidation, corrosion, etc., as curing catalysts for urethanes, as intermediates for preparing pharmaceuticals, etc.
摘要:
AN IMPROVED HIGH RETENTION LUBRICANT FOR TEXTILE-MACHINERY COMPRISES A NAPHTHENIC BASE OIL, A TACKINESS AGENT (E.G., POLYISOBUTYLENE), AND AN EFFECTIVE AMOUNT OF A LITHIUM SOAP (E.G. 0.1-1.5% LITHIUM STEARATE) TO PROVIDE A MECMICHAEL VISCOSITY AT 70* F. OF AT LEAST 15 (PREFERABLY 20-35). THE BASE OIL CAN HAVE A VISCOSITY IN THE RANGE OF 60-600 SUS AT 100* F. (MORE PREFERABLY 125300 SUS) AND AN ANILINE POINT IN THE RANGE OF 150-170* F., SAID BASE OIL COMPRISING AT LEAST ONE HYDROREFINED NAPHTHENIC OIL COMPONENT HAVING A VISCOSITY IN THE RANGE OF 40-12,000 SUS AT 100* F., AND PREFERABLY, IS A WIDE BOILING RANGE BLEND CONTAINING AT LEAST TWO SUCH HYDROREFINED NAPHTHENIC OILS. FOR EXAMPLE, THE LUBRICANT CAN COMPRISE 75 PARTS BY WEIGHT OF 100 SUS HYDROREFINED NAPHTHENIC OIL, 20 PARTS OF 2400 SUS HYDROREFINED NAPHTHENIC OIL, 2 PARTS OF A HIGH MOLECULAR WEIGHT (APPARENT M.W. IN OIL OF ABOUT 100,000) POLYISOBUTYLENE TACKINESS AGENT, 1 PART OF LITHIUM STEARATE, 1.5 PARTS OF CHLORINATED PARAFFIN AS AN ANTIWEAR AGENT, AND 5 P.P.M. OF SILICONE ANTIFOAM.

Organic compositions, which are normally susceptible of corroding copper, are provided, containing, in an amount sufficient to inhibit such corrosion an N-acyl benzotriazole.
摘要:
AN AERO GAS TURBINE LUBRICANT HAVING OUTSTANDING OXIDATION STABILITY, CORROSION RESISTANCE AND LOAD CARRYING ABILITY AND GOOD LOW TEMPERATURE FLUIDITY IS BASED ON A HINDERED ESTER AND CONTAINS AN ALKYLATED DIPHENYLAMINE AND AN ALKYLATED PHENYL NAPHTHYLAMINE AS ANTIOXIDANTS, A COPPER PASSIVATOR, A DISPERSANT POLYMER AND A NEUTRAL ORGANIC PHOSPHATE AS A LOAD-CARRYING ADDITIVE. A LEAD CORROSION INHIBITOR AND A HYDROLYTIC STABILITY IMPROVER MAY ALSO BE INCLUDED IN THE LUBRICANT.
摘要:
INTERPOLYMERS (ESPECIALLY COPOLYMERS) OF ETHYLENE AND PROPYLENE ARE OXIDIZED AND DEGRADED BY HEATING ABOVE 100* C. WITH AN OXYGEN-CONTAINING GAS, USUALLY AIR, IN THE PRESENCE OF AN ALIPHATIC AMINE. THE DEGRADED POLYMERS ARE CHARACTERIZED BY CAUSING SUBSTANTIALLY NO INCREASE IN THE LOW-TEMPERATURE FLUIDITY OF A FUEL OIL, AND ARE USEFUL AS VISCOSITY MODIFIERS FOR LUBRICANTS.
