Abstract:
OLEAGINOUS CRANKCASE LUBRICANTS CONTAINING PHOSPHOSULFURIZED HYDROCARBON POLYMER RESIST DETERIORATION DURING INSERVICE USE FOR INTERNAL COMBUSTION ENGINE LUBRICATION BUT THE PUNGENT, OBNOXIOUS ODOR AND CONTINUAL HYDROGEN SULFIDE EVOLUTION CHARACTERISTTIC OF SUCH PHOSPHOSULFURIZED HYDROCARBON DURING SUCH USE HAVE PREVENTED USE OF SAID OLEAGINOUS CRANKCASE LUBRICANTS. SAID ODOR AND INSTABILITY OF SUCH PHOSPHOSULFURIZED HYDROCARBON ARE IMPROVED BY ADDING THERETO A MINOR AMOUNT OF 2,5-BIS(ALKYLTHIO)-1,3,4THIADIAZOLE AND THE RESULTING COMPOSITION PROVIDES INHIBITION TO BEARING METAL CORROSION AND OXIDATIVE THICKENING OF OLEAGINOUS CRANKCASE LUBRICANTS.
Abstract:
The disclosure describes reaction products useful as multipurpose fuel and motor oil additives which are reaction products of about equal molar portions of (1) an intermediate product produced by the condensation reaction between about equal molar portions of a compound selected from the group consisting of an alkenyl substituted succinic acid, an alkenyl substituted succinic anhydride and an alkenyl substituted succinimide or metal salt thereof, said compound having an average molecular weight from about 350 to about 1,000, and a second compound selected from the group consisting of ammonia gas, ammonium hydroxide and hydrazine, and (2) a third compound selected from the group consisting of basic metal compounds, compounds with displaceable halogens, acid halides, alkylene oxides, acid anhydrides, thio anhydrides, triethyl phosphite, boric acid and acrylonitrile. The intermediate product was itself found to be useful as a fuel and motor oil additive.
Abstract:
The disclosure describes the reaction product produced by the reaction of about equal molar portions of (1) an alkyl benzene sulfonic acid, an alkyl sulfonic acid, an alkyl phosphorus acid or an alkyl carboxylic acid having an average molecular weight between about 200 and about 1600 and (2) a transition metal complexed with a polyamine.
Abstract:
The disclosure describes the reaction product produced by the reaction of about equal molar portions of (1) a polymeric succinic anhydride, polymeric succinic acid or polymer succinimide having an average molecular weight between about 250 and 2,500, and (2) a transition metal complexed with a polyamine.
Abstract:
THIS INVENTION CONCERNS THE CONDENSATION PRODUCT OF AN ALDEHYDE REACTANT HAVING MORE THAN ONE CARBON ATOM AND/OR KETONE REACTANT, FORMALDEHYDE, AN ALKYLENE POLYAMINE, AN ALKYL-SUBSTITUTED PHENOL, AND A METHYL-SUBSTITUTED AMINOPYRIDINE. THESE COMPOSITIONSCAN BE USED AS ASHLESS ALKALINE ADDITIVES FOR LUBRICATING OILS.
Abstract:
This invention concerns the condensation product of an aldehyde reactant having more than one carbon atom and/or ketone reactant, formaldehyde, an alkylene polyamine, and an alkyl-substituted phenol. These compositions can be used as ashless alkaline additives for lubricating oils.
