Abstract

The invention discloses a multifunctional additive for alcohol gasoline and a preparing method of the additive, and belongs to the technical field of gasoline additives. The multifunctional additive is prepared from, by weight, 25-30 parts of active amyl alcohol, 10-20 parts of normal propyl alcohol, 10-15 parts of diisooctyl phthalate, 8-10 parts of trinitrophenol, 5-8 parts of methyl ethyl ketone, 5-8 parts of isopropyl alcohol, 6-10 parts of carbomite, 2-5 parts of fatty glyceride, 2-5 parts of castor oil polyoxyethylene ether, 3-5 parts of diethylene glycol dibenzoic acid ester, 3-5 partsof lactic acid and 5-10 parts of p-hydroxy diphenylamine. The multifunctional additive for alcohol gasoline can be obtained by evenly mixing the raw materials according to a certain addition sequenceand conditions. The problems that existing alcohol gasoline is low in heat value, raw materials are not good in solubility, fuel is prone to layering when touching water, and alcohols have corrosivity, have a swelling property on rubber and are prone to colloid generation in use.

Description

technical field [0001] The invention belongs to the technical field of gasoline additives, and in particular relates to a multifunctional additive for alcohol gasoline and a preparation method thereof. Background technique [0002] With the continuous growth of car ownership, huge fuel consumption not only puts huge pressure on the increasingly depleted petroleum energy, but also easily produces toxin gases that pollute the environment after fuel combustion, and a large amount of pollutants discharged from improper fuel combustion have become a threat main factor of human existence. Alcohol fuel is a renewable raw material, which can be extracted or synthesized from raw materials such as grain, wood, coal, plant straw, natural gas, and potato. Compared with petroleum (hydrocarbon) fuel, alcohol fuel has a great competitive advantage, so alcohol fuel is considered as a promising and clean alternative fuel for internal combustion engines. [0003] The currently developed alc...
