Abstract

The invention relates to an ethanol gasoline additive, in particular to an ethanol gasoline stabilizer. The ethanol gasoline stabilizer consists of propanetriol, pentaerythritol, n-heptane, cyclohexanone, dimethyl carbonate, polyvinyl acetate, polyoxyethylene sorbitan oleate, ethyl acetoacetate, n-butyl amine oleate, hexamethylphosphoramide and dioctadecyl dimethyl ammonium chloride. The ethanol gasoline stabilizer is mainly applied to low-alcohol E10 ethanol gasoline as well as medium-alcohol E15 ethanol gasoline and high-alcohol E30 ethanol gasoline; when the ethanol gasoline stabilizer is used, with the weight of the ethanol gasoline as a reference, the ethanol gasoline stabilizer is added into the ethanol gasoline according to the adding amount of 1-5%, a phase stratification phenomenon of the ethanol gasoline can be effectively inhibited.

Description

technical field [0001] The invention relates to an ethanol gasoline additive, in particular to an ethanol gasoline stabilizer. Background technique [0002] At present, the United States has promoted and applied 10% ethanol gasoline (E10) throughout the country, and Brazil uses E22 ethanol gasoline, E10 and E30 dual-fuel engines. Since 2001, my country has promoted the implementation of two-phase national standards for "denatured ethanol" and ethanol gasoline for vehicles, and used and promoted E10 ethanol gasoline in Henan, Shandong, Jilin, Anhui and other places. [0003] Ethanol can increase the octane number of gasoline by 2-3 units. The octane number of catalytic cracking gasoline with the research method octane number is 90.6. When 10% ethanol gasoline is added, the octane number can reach 93, which meets the standard requirements of No. 93 gasoline. [0004] However, ethanol gasoline also has its own shortcomings, the main problem is the problem of stability. Anhydr...
