Abstract:
Ammonium salt of alkyl alkanephosphonates represented by the formula:
IN WHICH R is a substantially straight chain aliphatic radical having from about 11 to 40 carbon atoms, R'' is a lower aliphatic radical having from one to eight carbon atoms, R2 is a hydrocarbyl radical having from 1 to 40 carbon atoms and R3 and R4 are hydrogen, a hydrocarbyl radical having from one to 40 carbon atoms, or a substituted hydrocarbyl radical having amino, alkylamino or hydroxyl functional groups, the reaction of preparing same from an ester of an alkanephosphonic acid, and a lubricating oil composition containing an ammonium alkyl alkanephosphonate.
Abstract:
A lubricating oil composition of improved corrosion, wear and oxidation inhibiting properties consisting of a hydrocarbon lubricating oil composition comprising a major amount of hydrocarbon lubricating oil and between about 0.1 and 10 wt. percent of tetra-t-dodecylmercapto-p-benzoquinone and optionally including additional automative lubricating oil additives such as VI improvers, detergent-dispersants, anti-foamants and supplementary corrosion, wear and oxidation inhibitors.
Abstract:
THIS INVENTION CONCERNS SYNERGESTIC COMBINATIONS OF INORGANIC NITRITES AND CERTAIN AMINES WHICH WHEN INCORPORATED INTO ALKALI-METAL SOAP AND/OR ALKALINE EARTH METAL SOAP BASED GREASES INHIBIT CORROSION.
Abstract:
Separation of cyclohexylbenzene hydroperoxide from, for example, a mixture of cyclohexylbenzene and its oxidation products is accomplished by extraction of the oxidation products by means of polyurethane foam. Separation of the oxidation products is achieved in a two step desorption operation.
Abstract:
Automatic transmission fluid comprising at least 86 weight percent of a mineral lubricating oil and 0.01 to 5.0 weight percent of an alkanephosphonic acid salt represented by the formula:
IN WHICH R is a straight chain or predominantly straight chain aliphatic radical having from about 11 to 40 carbon atoms, M is zinc, calcium or an alkyl ammonium radical having the formula:
IN WHICH R'''' is a polymethylene radical having from two to four carbon atoms, R'' is an alkyl radical having from six to 20 carbon atoms and x is 1 or 2 equal to the valence of M, and a method for operating an automatic transmission.
