摘要:
Borated hydroxyalkyl esters of alkyl- or alkenylsuccinimide-derived dithiocarbamic acids, have been found to be effective multifunctional additives in lubricant and fuel applications.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
The load carrying ability of a lubricant is improved by adding to such lubricant an effective amount of diorganophosphorus derivative of urethane (ethyl carbamate).
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
Lubricants are stabilized against oxidation by adding thereto a stabilizing amount of an ester of a hindered hydroquinone. An example of a suitable material is (4-hydroxy-3,5-di-t-butylphenyl)laurate.
