Alcohol base gasoline solubilizer and preparation method thereof

Abstract

The invention discloses alcohol base gasoline solubilizer and a preparation method thereof. The solubilizer comprises isopropyl ether, acetamide, alkylphenol polyether, methyl tert-butyl ether, fatty acid methyl ester, furan, tertiary butanol, antioxidant and anti-swelling agent. The preparation method comprises the following steps: weighing isopropyl ether, tertiary butanol, acetamide, alkylphenol polyether, methyl tert-butyl ether, fatty acid methyl ester, furan, antioxidant and anti-swelling agent according to a certain weight ratio, adding isopropyl ether and tertiary butanol in a reaction kettle for vacuumization, warming the reaction kettle, adding acetamide, stirring, adding alkylphenol polyether, stirring and cooling through a cooler, adding methyl tert-butyl ether, fatty acid methyl ester, furan, antioxidant and anti-swelling agent, and uniformly stirring to obtain the alcohol base gasoline solubilizer. The invention has no toxicity, no pollution and no special odor, less adding amount, good solubilizing effect, and no heavy metal component, no generation of new pollution and no mechanical impurity, and can increase the octane of 90# gasoline to 95-99#.

Description

Technical field: [0001] The invention relates to a co-solvent for methanol gasoline, in particular to an alcohol-based gasoline co-solvent and a preparation method. Background technique: [0002] In recent years, as international oil prices continue to hover at high levels, the promotion and application of domestic alternative alcohol-ether fuels has been accelerated. According to the implementation of the strategic policy of energy substitution promulgated by the National Development and Reform Commission, people began to experiment with methanol gasoline co-solvent. Corrosion, anti-rust, anti-turbidity, anti-oxidation, inhibit rubber expansion, enhance power, etc. Co-solvent prepared by traditional process, immature chemical additive technology and blending technology lead to toxic gas emission, corrosion, swelling, delamination / emulsification when encountering water, high-temperature air resistance, difficulty in starting at low temperature, no drop in power, increased f...

AI Technical Summary

Problems solved by technology

Co-solvent prepared by traditional process, immature chemical additive technology and blending technology lead to toxic gas emission, corrosion, swelling, delamination / emulsification when encountering water, high-temperature air resistance, difficulty in starting at low temperature, no drop in power, increased fuel consumption, etc. series of questions

[0003] People are studying the use of pure organic compounds as methanol gasoline co-solvents. For example, a kind of methanol gas co-solvent for short HFA has been produced and used in some European countries. It has a small amount and has quite good corrosion resistance. It has poor stability and the defect of separation layer when it meets water

[0004] There are six major problems in the prior art: 1. Poor compatibility of raw materials used; 2. Decreased power and low calorific value; 3. Separation when encountering water; 4. Poor cold start effect, and the use in cold regions in winter is subject to certain limitations; 5. , corrosion problems; 6, high temperature is prone to air resistance
