High-efficiency additive for methanol gasoline and preparation method of additive

Abstract

The invention discloses a high-efficiency additive for methanol gasoline and a preparation method of the additive. The additive for the methanol gasoline is prepared from the following components, inparts by weight: 9-11 parts of 1,5-dimethylhexylamine, 13-16 parts of o-toluidine, 2-8 parts of dilinoleic acid, 5-10 parts of succinic anhydride, 6-10 parts of a cellosolve, 10-14 parts of a rare earth salt, 8-12 parts of an alcohol, 1-5 parts of an emulsifier, and 30-60 parts of hydrocarbons. The additive provided by the invention enhances stability of the methanol gasoline, improves dynamic properties of the methanol gasoline, improves corrosivity of the methanol gasoline, inhibits swelling of the methanol gasoline, improves gas resistance of the methanol gasoline, and improves cold startability of the methanol gasoline.

Description

technical field [0001] The invention relates to the field of methanol gasoline, in particular to a high-efficiency methanol gasoline additive and a preparation method thereof. Background technique [0002] With the continuous advancement of science and technology, the continuous development of the economy, the consumption of energy is also increasing. At present, the amount of oil consumed in the world is also increasing. Life, industry, etc. cannot do without oil. Of course, the exploitation of oil is also increasing It is becoming more and more difficult. Therefore, people are now researching new energy sources. Methanol gasoline has solved various problems caused by ordinary gasoline, and reduced environmental pollution and high energy consumption. However, methanol gasoline also has corresponding problems, such as poor stability. , water stratification, cold start difficulty, low calorific value, insufficient power, thermal air resistance, corrosion and swelling, etc. Me...
