Borated hydroxyalkyl esters of alkyl- or alkenylsuccinimide-derived dithiocarbamic acids, have been found to be effective multifunctional additives in lubricant and fuel applications.

Borated hydroxyalkyl esters of alkyl- or alkenylsuccinimide-derived

Lubricating oil and grease compositions contain borated hydroxyalkyl esters of amine or metal salts of diorganodithiocarbamic acid, such as N,N'-di-(2-ethylhexyl) dithiocarbamic acid, and hydrocarbylene oxie, such as propylene oxide, as antioxidant, load-carrying and friction modifying additives.

Borated hydroxyalkyl esters of dithiocarbamic acids as multifunctional

Products derived from the reaction of organic or metal salts of diorganodithiocarbamic acids with benzenesulfonyl halides, impart excellent multifunctional antiwear and antioxidant properties to lubricating oil compositions.

Benzenesulfonyl derivatives of N,N-diorganodithocarbamic acids as

Disclosed are products derived from the reaction of amine or metal salts of N,N-diorganodithiocarbamic acids with organo phosphorus halides. These compositions are useful as antioxidants and antiwear additives in lubricating oil compositions.

N,N-diorganodithiocarbamate derivatives and lubricant compositions

Disclosed are products derived from the reaction of amine or metal salts of N,N-diorganodithiocarbamic acids with thionyl chloride, SOCl.sub.2. These compositions are useful as antioxidants and antiwear additives in lubricating oil compositions.

Reaction products of N,N-diorganodithiocarbamates with thionyl chloride

Disclosed are products derived from the reaction of amine or metal salts of N,N-diorganodithiocarbamic acids with alkylthiosulfinyl halides. These compositions are useful as antioxidants and antiwear additives in lubricating oil compositions.

N,N-diorganodithiocarbamate-alkylthiosulfinyl halide reaction products

Multifunctional (antiwear/anitoxidant) additives prepared by reaction of diorganophosphorodithioic acids and a sulfurous-oxyhalide, e.g. thionyl chloride impart resistance to oxidation and abrasion when incorporated into lubricating oils.

Non-metallic multifunctional lubricant additives and compositions thereof

Method for making methylene-bis-diorganophosphorodithiato-substituted hindered phenols by conversion of hindered phenols to the corresponding hindered phenol aldehydes and subsequent reaction, without isolation, with a diorganophosphorodithioic acid, which results in economically advantageous and simplified processing as well as minimization of wasteful and costly by-products.

Method for preparing a

Lubricants are stabilized against wear and corrosion by adding an additive amount of a novel substituted thiadiazole. These are derived from 2,5-dimercapto-1,3,4-thiadiazole and other moieties, as for example, an isocyanate moiety.

Substituted dimercapto thiadiazoles and lubricant compositions

Product made by reacting a hindered phenol aldehyde with a primary amine followed by reacting the product thus obtained with a diorganophosphorodithioic acid, and lubricants containing same.

Phosphorodithioate products of hydrocarbyl imino-methylene-substituted

Reaction products of selected inorganic thiocyanates and alkyl or aryl phosphorus halides provide additive compounds which impart excellent antiwear and load-carrying protection to lubricant base stocks in which they are incorporated.

Reaction products of organophosphorus halides with inorganic

Adducts of alkylphosphorous triamides with alpha, beta-unsaturated carbonyl compounds provide novel sulfur-free load-carrying additives for various organic compositions, e.g., lubricant oils.
