Problems solved by technology

The addition of xylene will significantly increase the emission of toxic substances in the exhaust gas, which is not conducive to environmental protection and human health
[0009] At the same time, there are still many deficiencies in the current research on improving the anti-phase separation performance of methanol gasoline: 1. The proposal is only proposed from the perspective of anti-phase separation theory, without comprehensive consideration of whether additives can be added to vehicle fuels to meet the requirements of engines, vehicles and exhaust emissions Some raw materials of additives are not conducive to the development trend of vehicle fuel emission reduction and pollution reduction; 2. The preparation process of additives is complicated and the economy is poor; 3. Some raw materials of additives are untreated residues and residues, which are toxic and exhaust emissions Exceeding the risk

Abstract

The invention relates to an M20 methanol gasoline denatured alcohol additive, prepared from 15-20% of 1-cyano-2-propenyl acetate, 10-20% of 3-cyclohexene-1-methanol, 10-20% of 5-methyl-2-hepten-4-one, 12-20% of 1-acetamido-3-amino-2-methylpropane, 10-20% of 4-methyl-2-pentanone, 8-15% of 3-aminobenzylmethylamine, 5-10% of a-benzylhydrocinnamic acid, and 10-15% of 2-ethoxyethanol by blending; M20 methanol gasoline denatured alcohol additive is used for being added to methanol in order to prepare denatured alcohol, and the usage of the additive accounts for 0.2-0.5% of total mass of the denatured alcohol. M20 methanol gasoline prepared with the denatured alcohol with the additive has significantly improved phase separation resistance and may meet the requirement for long-term storage in low-temperature high-humidity environment.

Description

technical field [0001] The invention belongs to the technical field of methanol replacing vehicle fuel, and relates to an additive for denatured alcohol of methanol gasoline, in particular to a denatured alcohol additive suitable for M20 methanol gasoline. Background technique [0002] Energy and environmental issues restrict the rapid development of my country's economy.
