The instant invention relates to a lubricant composition stabilized against the deleterious effects of heat and oxygen. The composition comprises a triglyceride oil or an oil which is an ester wherein unsaturation is present in either the alcohol moiety or the acid moiety and an effective stabilizing amount of either an N,N-disubstituted aminomethyl-1,2,4-triazole or an N,N-disubstituted aminomethylbenzotriazole; a higher alkyl substituted amide of dodecylene succinic acid; a phenolic antioxidant; and an aromatic amine antioxidant. Further additives can be added to these lubricant formulations.
摘要:
This invention relates to a two-stroke engine oil which comprises polybutene base oils which are either very low in or are substantially free of n-butenes in the polymer backbone. The absence of n-butenes in the polybutenes significantly reduces smoke emission in exhaust gases generated by the use of the engine oil. Polybutenes such as ULTRAVIS.RTM. which are substantially free of chlorine and have a high degree of terminal unsaturation are particularly preferred.

摘要:
PROCESSES FOR PREPARING BASIC MAGNESIUM SALTS OF OIL SOLUBLE ORGANIC ACIDS BY CONTACTING AN INORGANIC ACIDIC MATERIAL WITH A MIXTURE OF THE ACIDS, OR THEIR ALKALI OR ALKALINE EARTH METAL SALTS, MAGNESIUM OXIDE, AND WATER OR ALCOHOL-WATER PROMOTER SYSTEM. CARBON DIOXIDE IS AN EXEMPLARY ACIDIC MATERIAL. LOWER ALKANOLS PARTICULARLY METHANOL, ARE USEFUL CO-PROMOTERS FOR USE WITH THE WATER. MIXTURES OF OIL-SOLUBLE SULFONIC ACIDS AND OIL-SOLUBLE CARBOXYLIC ACIDS, OR THEIR ALKALI OR ALKALINE EARTH METAL SALTS, ARE USEFUL STARTING MATERIALS FOR PREPARING BASIC MAGNESIUM SALTS. WITH ALCOHOL-WATER CO-PROMOTERS, THE INORGANIC ACIDIC MATERIAL IS CONTACTED WITH THE REACTION MIXTURE IN TWO STAGES, FIRST IN THE PRESENCE OF BOTH PROMOTERS AND THEN IN THE PRESENCE OF WATER ONLY. THE PRODUCTS ARE USEFUL AS ADDITIVES IN LUBRICANTS AND FUELS AND AS INTERMEDIATES IN PREPARING OTHER USEFUL PRODUCTS.
