Ethanol gasoline phase stabilizer and preparation method thereof

Abstract

The invention discloses an ethanol gasoline phase stabilizer. The stabilizer consists of the following raw materials in part by weight: 10 to 28 parts of isopropyl alcohol, 10 to 28 parts of isooctyl slcohol, 10 to 28 parts of normal heptane, 5 to 7 parts of methyl carbonate, 5 to 7 parts of diethyl phthalate, 5 to 7 parts of methyl isobutyrate, 1 to 2 parts of polyoxyethylene sorbitan monooleate, 1 to 2 parts of acetacetic ether, 1 to 3 parts of oleic acid n-butylamine, 1 to 3 parts of hexamethylphosphoramide, 1 to 2 parts of cyclohexanone, and 1 to 2 parts of hexadecyl dimethly ammonium chloride. The invention also discloses a method for preparing the ethanol gasoline phase stabilizer. The ethanol gasoline phase stabilizer of the invention can effectively improve the phase stability of ethanol gasoline products; when the ethanol gasoline phase stabilizer is used, the ethanol gasoline product is not layered when being stored for 6 months; and the additive also has the advantages of corrosion resistance, good detergent dispersing effect, easy preparation and convenient popularization and application.

Description

Ethanol gasoline phase stabilizer and preparation method thereof technical field The invention relates to an ethanol gasoline phase stabilizer, and also relates to a preparation method of the stabilizer. Background technique Ethanol began to be used as a motor fuel in the 1930s, but its application decreased due to the large-scale development of petroleum resources and relatively low cost. Since the 1970s, due to the impact of the oil crisis and the limitation of automobile emissions, the fuel ethanol industry has developed rapidly in many countries in the world. There are three reasons why the use of alcohol-containing fuels has been re-emphasized: one is to alleviate the contradiction of shortage of oil resources; the other is to improve vehicle exhaust emissions and reduce environmental pollution; the third is to promote the transformation of agricultural products and increase farmers' income. The raw material used to produce ethanol in the United States is mainly corn...
