摘要:
A diesel crankcase lubricant composition comprising a lubricating oil base and the reaction product of a hydrocarbyl succinic anhydride in which the hydrocarbyl radical has from 12 to 30 carbon atoms and 5-amino-triazole is provided.
摘要:
A rust inhibitor comprising the reaction product of a hydrocarbylsuccinic anhydride in which the hydrocarbyl radical has from about 6 to 30 carbon atoms and an aminotriazole is provided. The rust inhibitor is effective in motor fuel and lubricating oil compositions.
摘要:
Motor fuel composition comprising a mixture of hydrocarbons in the gasoline boiling range containing a minor detergent amount of an aminimide represented by the formula: ##STR1## in which R' is a hydrocarbon radical having from about 10 to 24 carbon atoms and R is hydrogen or a hydrocarbon radical having from 1 to 20 carbon atoms.
摘要:
A composition of matter comprising ureas, biurets or allophanates structurally represented, respectively, by ##STR1## where R is hydrogen or a (C.sub.1 -C.sub.50) linear or branched aliphatic, alkenyl, alkynyl or aryl hydrocarbon; ##STR2## where R is hydrogen or a (C.sub.1 -C.sub.50) linear or branched aliphatic, alkenyl, alkynyl or aryl hydrocarbon; or ##STR3## where R is hydrogen or a (C.sub.1 -C.sub.50) linear or branched aliphatic, alkenyl, alkynyl or aryl hydrocarbon.
摘要:
A liquid jet fuel composition comprising:(a) a major portion of a liquid fuel; and(b) a minor effective portion of a thermal stabilizing additive prepared by(i) reacting a polyamine, an aldehyde and a phenol containing active hydrogen to form a phenol - aldehyde - amine condensate; and(ii) reacting said phenol - aldehyde - amine condensate and a succinic acid anhydride bearing a polyolefin - derived substituent containing residual unsaturation, thereby forming a phenol - aldehyde amine Mannich condensate polyamine succinimide product additive; and(iii) recovering said product additive.
