A sulfided carbon support catalyst bearing (i) a non-noble Group VIII metal, (ii) a Group VI-B metal, and (iii) a metal of Group IA, II A, III-B, or the lanthanide Group of rare earths.

Hydrotreating of cracked naphtha

Hydrodesulfurization of cracked naphtha, with minimum attendant hydrogenation of olefins, is effected over a sulfided carbon support catalyst bearing (i) a non-noble Group VIII metal, (ii) a Group VI-B metal, and (iii) a metal of Group IA, II A, III B, or the lanthanide Group of rare earths.

An amine salt of N-triazolyl-hydrocarbyl succinamic acid represented by the formula: ##STR1## in which R'' is an alkylene radical having from 2 to 24 carbon atoms and R'' is hydrogen or a hydrocarbyl radical having from 1 to 24 carbon atoms at least one R'' being a hydrocarbyl radical and a lubricating oil composition containing same is provided.

Amine salt of N-triazolyl-hydrocarbyl succinamic acid and lubricating

Synthetic lubricating oil composition comprising a major portion of an aliphatic ester base oil having lubricating properties formed from the reaction of a pentaerythritol or trimethylolpropane and an organic monocarboxylic acid containing (a) from about 0.01 to 0.5 percent of a substituted 4-aminotriazole; (b) from about 0.3 to 5 percent of an alkyl or alkaryl phenylnaphthylamine; (c) from about 0.3 to 5 percent of a dialkyldiphenylamine; and (d) from about 0.25 to 10 percent of a hydrocarbyl phosphate ester.

Synthetic aircraft turbine oil

Method of carboxylating a compound of the group of R-C.tbd.CH, RCH.sub.2 CN, indene, cyclopentadiene or fluorene, where R is hydrocarbyl, comprising contacting said compound with carbon dioxide under substantially anhydrous conditions in the presence of a base of the formula: ##SPC1## Where X is sodium or potassium, R.sup.1 is hydrogen or alkyl and subsequently acidifying the resultant reaction product to form the carboxylated product.

Carboxylation of compounds

A method of producing an alkyl amine salt of thiocyanic acid having enhanced load-carrying properties when employed in synthetic ester lubricating oils comprising contacting an alkyl amine with ammonium thiocyanate or monoalkyl ammonium thiocyanate at an elevated temperature while continuously blowing the reaction mixture with an oxygen containing gas and recovering the formed alkyl ammonium thiocyanate salt, the oxygen containing gas being introduced into the reaction mixture in a total amount of between about 0.2 and 5.0 moles per equivalent weight of amine; and synthetic ester oil compositions containing a load-carrying additive amount of the alkyl ammonium thiocyanate prepared by said method.
