摘要:
NOVEL COMPOUNDS ARE PREPARED BY REACTING A DI(ORGANO), PREFERABLY A DIHYDROCARBYL, PHOSPHORODITHIOATE WITH A DI(ORGANO), PREFERABLY A DIHYDROCARBYL, CARBODIIMIDE. THESE COMPOUNDS POSSESS EXCELLENT ANTIOXIDANT PROPERTIES AND CAN BE USED IN INDUSTRIAL ORGANIC FLUIDS. SUCH AS LUBRICATING OILS, HYDRAULIC FLUIDS AND THE LIKE. DIARYLPHOSPHORODITHIOATES ARE PREFERRED REACTANTS.
摘要:
Dimers of diarylamines are prepared by a process comprising treating a diarylamine-perchlorate salt with an oxidizing agent in an acidic medium. Exemplary of the products obtained is 4,4''dianilino-1,1''-binaphthyl, which is made by treating N-phenylAlpha -naphthylamine-perchlorate with chromium trioxide in acetic acid and water. The products thus produced are useful antioxidants in lubricants.
摘要:
Lubricants are stabilized against oxidative degradation by adding thereto a stabilizing amount of an ester of an anthranilic acid. An example of a suitable material is n-octyl Nnaphthylanthranilate (n-octyl N-phenyl-1-naphthyl-2''carboxylate).
摘要:
ORGANIC COMPOSITIONS, NORMALLY SUSCEPTIBLE TO OXIDATIVE DETERIORATION, CONTAINING, IN AN AMOUNT SUFFICIENT TO INCREASE OXIDATION RESISTANCE, A SYNERGISTIC MIXTURE OF 1-NBUTOXY-1-(1-NAPHTHOXY) ETHANE AND A CO-ANTIOXIDANT SELECTED FROM THE GROUP CONSISTING OF T-NONYLPOLYSULFIDE, PHENYLTHIOBENZOQUINONE AND DIOCTYLDIPHENYLAMINE.
摘要:
THE ADDITION OF AN ADDITIVE MADE BY REACTING A PHOSPHONATE WITH OLEAMIDE TO A LUBRICANT IMPARTS IMPROVED FRICTIONAL CHARACTERISTICS THERETO. IN ADDITION, LEVELS OF CORROSION AND CHATTER AND SQUAWKING NOISES RESULTING FROM INTERRUPTED POWER TRANSMISSION ARE ELIMINATED OR REDUCED TO ACCEPTABLE LEVELS.
摘要:
NOVEL ESTERS OF O,O-DIORGANO - S - (2 - HYDROXYALKYL) PHOSPHORODITHIOATES ARE EXCELLENT ANTIOXIDANTS AND CORROSION INHIBITORS IN INDUSTRIAL FLUID COMPOSITION. THIS APLLICATION IS SPECIFICALLY CONCERNED WITH ESTER PREPARED FROM THE PHOSPHORODITHIOATE AND A PHOSPHORUS-CONTAINING COMPOUND.
