Abstract
1417590 Fuel/lubricant mixtures; lubricants INSTITUT FRANCAIS DU PETROLE 28 Dec 1972 [31 Dec 1971]. 59900/72 Headings C5G and C5F A fuel-lubricant mixture, for feeding 2-stroke engines, consists of a gasoline fuel and 0À1-2wt. per cent of lubricating composition consisting of a major proportion of a lubricant having a viscosity at 98À9 C. of at least 6 centistokes which consists of 10-100 wt. per cent of at least one ester, selected from 2 defined classes and having a viscosity at 98À9 C. of at least 6 centistokes, of polyalkylene glycols of general formula, HO(RO) n H where R = alkylene radical of 2-5 carbon atoms and n = 2-50, the balance if any of the lubricant consisting of a mineral or synthetic lubricating oil, or a diluent, or a mixture of two or more thereof, the balance if any of the lubricating composition being constituted by conventional lubricant additives. Other methods of introducing lubricant into a 2-stroke engine include mixing with the gasoline-air mixture. In one class the esters conform with the Formulµ (I-IV) where R 1 and R 2 are both identical or different and are the hydrocarbyl (e.g. C 1 -C 25 ) residues of a monohydroxy compound (e.g. monoalcohol or monophenol), R 1 <SP>1</SP> is the hydrocarbyl (e.g. C 3 -C 20 ) residue of a polyhydoxy compound, R 3 is the hydrocarbyl residue (e.g. C 1 -C 34 ) of a dicarboxylic acid and m is 2-4. In the second class the esters conform with the formulµ where the symbols R 1 , R 2 and R 3 are defined as above, R<SP>1</SP> as R, k as n, and p is greater than 1. In esters of Formulµ VII-XI at least a portion of the polyalkylene glycol residue may be replaced by a residue of a polyalkylene glycol ether of the formula in which R 1 <SP>1</SP> and m are as defined above. The synthetic lubricating oils may be oligomers or polymers of olefinic hydrocarbons, e.g. polybutenes or their hydrogenated form, simple esters, complex esters or polyesters of monoalcohols or polyols, e.g. isodecyl adipate, 2- ethyl-hexyl azelate or trimethylol propane caprylate. The diluents may be white spirit, kerosene, jet-fuel, aromatic solvents, alcohols (e.g. isononanol), ketones, e.g. cyclohexanone or certain esters (e.g. acetates or propionates of heavy alcohols). Lubricant additives may be antioxidants, e.g. phenolic or amine additives, detergents, organo salts, ashless dispersing agents and halogenated derivatives, e.g. ethylene dibromide. The examples illustrate various of the esters of polyalkyleneglycol.
