摘要:
The invention provides methods of preparing organophilic clays having enhanced dispersibility in organic liquids, the organophilic clay containing gellants, and methods of increasing the viscosity of organic liquids utilizing these gellants.
摘要:
Grease compositions containing nitrites and amines form N-nitrosamines, which are suppressed by the addition to such compositions of a combination of metal ascorbate or metal isoascorbate with alpha tocopherol.
摘要:
The color and viscosity stability of copolymeric .alpha.-olefin viscosity index improvers and of oils containing same are improved by the incorporation therein of minor amounts of N,N'-bis(2-hydroxy-5-alkylbenzyl).alpha.-.OMEGA.-diaminoethane wherein the alkyl group is a C.sub.4 to C.sub.30 alkyl group and the basic metal salts thereof.
摘要:
Disclosed are novel synthetic lubricants containing major amounts of tertiary diamides having the following structural formula: ##EQU1## wherein N = 4-12 ##EQU2## wherein R = H, alkyl radical having C.sub.1 -C.sub.5m = 2-8x = 1-5These lubricants have low pour points and excellent thermal stabilities.
摘要:
A method for preserving certain organic fluids is provided wherein an inhibitory amount of a selected 1,10-phenanthroline is incorporated in such fluids as a biocide.
摘要:
A grease composition is disclosed comprising (a) a lubricating oil base, (b) a mono or polyurea thickener, (c) a Mannich Base prepared by reacting formaldehyde, phenol and an amine selected from diethanolamine, N,N-diethanol alkylenediamine, and diethylamine, and (d) an alkaline earth metal aliphatic monocarboxylate having from 1 to 3 carbons.
摘要:
1. A GREASE COMPOSITION HAVING SUPERIOR SHEAR STABILITY, WATER-RESISTANCE AND EXTREME PRESSURE PROPERTIES, COMPRISING FROM ABOUT 65 TO 90 WEIGHT PERCENT OF LUBRICATING MINERAL IOL FROM ABOUT 35 TO 10 WEIGHT PERCENT OF A THICKENING SYSTEM MADE UP OF 25 TO 9 WEIGHT PERCENT OF FIBROUS ASBESTOS AND ABOUT 10 TO 1 WEIGHT PERCENT OF POLYMERIC COATIG AGENT HAVING RECURRING UNITS INCLUDED WITHIN THE STRUCTURES:
(1,2,2,3,4-PENTA(R)-1,2-DIHYDRO-QUINOLINYL-R)N
WHEREIN THE AVERAGE DEGREE OF POLYMERIZATION RANGES FROM 2 TO ABOUT 10, AND R IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, ALKYL RADICALS AND HYDROXYLATD ALKYL RADICALS, SAID ALKYL RADICALS CONTAINING FROM 1 TO 6 CARBON ATOMS.
摘要:
GREASE COMPOSITIONS COMPRISING AN OLEAGINOUS BASE VEHICLE HAVING INCORPORATED THEREIN A MINOR AMOUNT OF A DIURETHANE-DIUREA THICKENING AGENT HAVE EXCELLENT HIGH TEMPERATURE DYNAMIC LUBRICATING PROPERTIES. THE DIURETHANE-DIUREA THICKENERS ARE PRODUCED FROM DIHYDRIC ALCOHOLS, DIISOCYANATES AND MONOAMINES.
