Environmental-friendly methanol gasoline multifunctional synergist

Abstract

The invention provides an environmental-friendly methanol gasoline multifunctional synergist which comprises the following components in parts by weight: 35-45 parts of methyl tertiary butyl ether, 20-30 parts of methyl formate, 20-30 parts of dimethylbenzene, 10-20 parts of alkyl isopropanol, 3-20 parts of tertiary butanol, 0.1-0.5 part of dicyclopentadienyl iron, 0.05-0.1 part of hydroxy benzotriazole, 0.5-1 part of dodecyl 2-ethylhexanoate and 0.1 part of triethanolamine. The synergist has low cost, easy obtaining of raw materials and remarkable synergizing effect; the mixed methanol gasoline has power equal to No.93 gasoline and the addition amount of commonly 3-5 in the methanol gasoline, and ensures that the emission of Co in the tail gas is greatly reduced; and the methanol gasoline after the addition has good stability and comprehensive cost reduced by over 30 percent, and is mainly used as a methanol gasoline additive.

Description

technical field [0001] The invention relates to a gasoline additive, in particular to an environment-friendly multifunctional synergist for methanol gasoline. Background technique [0002] Energy shortage and environmental degradation have become urgent problems in the world recently. Gasoline is the main source of power for automobiles. In addition to its rising price, CO emissions are also one of the factors causing environmental degradation. At present, part of gasoline is replaced by methanol to achieve the purpose of reducing cost and CO emissions in tail gas. However, due to the structural characteristics of methanol molecules, methanol gasoline additives must be added to increase its compatibility with gasoline and maintain the performance of the original gasoline. Chinese patent 101215484 discloses a methanol gasoline additive. The components include 25-30 parts by weight of methanol, 5-10 parts of isobutanol, 10-15 parts of oleic acid, 1-3 parts of dimethyl carbona...

AI Technical Summary

Problems solved by technology

Since the surface-active emulsifiers such as Tween 80 are high-molecular compounds, they are easy to form carbon in the alcohol oil, the combustion is insufficient, and there are many components, the cost is high, the production process is complicated, and heating reactions are required, etc.
