摘要:
The spreadability of marine diesel cylinder oils is improved by the incorporation therein of a spreadability improving amount of a polyalkoxylated phenoxy compound having the formula: ##STR1## wherein R is an aliphatic hydrocarbyl group having from 5 to 70 carbon atoms and n ranges from 14 to 30.
摘要:
A diesel lubricant composition comprising a lubrication oil base and a corrosion-inhibiting amount of at least one benzotriazole, N-alkyl-1,3-propanediamine and formaldehyde condensation product.
摘要:
Lubricant oil comprising a hydrocarbon oil of lubricating viscosity, a sulfurized overbased calcium alkylphenolate detergent-inhibitor having a calcium metal to alkylphenol ratio of at least 2.9:2; and a sulfurized naphthenic base oil-contaning composition having a sulfur content of from 1 percent to 6 percent by weight.
摘要:
Lubricant oil comprising a hydrocarbon oil of lubricating viscosity, a highly overbased alkaline earth metal-containing alkylphenolate detergent-dispersant composition sufficient to impart a total base number to said lubricant oil of at least 10; and a chlorinated sulfurized alkylphenol.
摘要:
An oxidation and corrosion resistant diesel engine lubricant composition, particularly useful in marine and railway diesel engines, comprises a major amount of a base hydrocarbon lubricating oil and from 0.1-5.0 weight percent of a reaction product additive which is the reaction product of an N-acyl sarcosine and a substituted or unsubstituted heterocyclic azole.
摘要:
A haze, oxidation, and corrosion resistant diesel engine lubricant composition, particularly useful in marine and railway diesel engines, contains 0.1-5.0 weight percent of a reaction product additive. The reaction product additive is produced by first reacting substantially equimolar amounts of an anhydride compound which is either a dibasic acid anhydride or isatoic anhydride and a hydrocarbon-substituted mono primary amine or ether amine at a temperature range of 50.degree. C.-150.degree. C. to produce an intermediate reaction product. The intermediate reaction product is thereafter further reacted at an elevated temperature with a substantially equimolar amount of a heterocyclic azole or polyalkylene polyamine compound to form the final reaction product.
摘要:
A crankcase lubricating oil composition for railway diesel engines, containing a mineral lubricating oil, an overbased calcium alkylphenolate and an alkyaryl sulfonate oxidation and corrosion inhibiting amount of a reaction product of polyoxyisopropylene diamine, dibasic acid anhydride and polyalkylene polyamine.
摘要:
The ability of marine diesel engine cylinder lubricants is improved by the incorporation therein of a spreadability improving amount of at least one polyoxyethylene ester of the formula: ##STR1## wherein n ranges from 18 to 22 and R is an alkyl group having 11 to 17 carbon atoms in the chain.
