TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The low temperature resistant alcohol clean fuel oil further comprises (in weight%): combustion accelerant (0.5-1), cleaning dispersant (0.03-0.8), corrosion inhibitor (0.05-1), metal passivant (0.01-0.06), antioxidant (0.3-1), oil stabilizer (0.1-0.5), anti-detonation agent (0.2-0.5), calorific value improving agent (0.5-1.0), solubilizing agent (1.5-5), emulsifier (0.5-1.0) and plasticizing agent (0.05-0.5). The combustion accelerant is prepared using ethanol, acetone and hydrogen peroxide in the volume ratio of 1: 1: 1. Preferred Components: The cleaning dispersant is one or more of monosuccinimide, polyolefine succinimide and polyetheramine. The anti-corrosive inhibitor is one or mixture of fatty acid ester, dicyclohexylamine nitrite, isopropanol, dibutylamine and glycerol triacetate. The metal passivant is one or mixture of N,N-disalicylidene-1,2-ethylenediamine, N,N-disalicylidene-1,2-propanediamine and 2-cyclohexanediamine. The antioxidant is one or more of 2,6-di-tert-butyl-4-hydroxytoluene, 4-hydroxy-diphenylamine and 2,6-di-tert-butylphenol. The oil stabilizer is isobutyl amine. The anti-detonation agent is one or mixture of methylcyclodienyl manganese tricarbonyl, aniline, triethyl aniline and xylidine. The calorific value improving agent is one or mixture of heptanol, isopropyl ether, dodecane and 2,4-trimethylpentane. The solubilizing agent is one or mixture of petroleum ether, orthoxylene, butanone, cyclohexanone, acetylacetone, ethyl isobutyrate and diethyl carbonate. The emulsifier is one or mixture of surfactant, normal butanol and sec-butyl alcohol. The plasticizing agent is one or mixture of oleic acid, dibutylamine, glycerol triacetate and dimethyl phenol. The surfactant is anionic surfactant and/or non-ionic surfactant. The anionic surfactant is fatty acid ester salt, fatty acid anilide or alkylbenzene sulfonate. The non-ionic surfactant is polyoxyethylene alkyl ether, polyoxyethylene alkyl ether or alcohol amine.
