Problems solved by technology

[0003] The main components of methanol gasoline are composed of methanol and gasoline. After methanol is mixed with component oil, the original self-association of methanol is destroyed, thus causing a positive deviation effect that the saturated vapor pressure of methanol gasoline is higher than the vapor pressure of the component oil itself. Generally, the range is 10kpa-15kpa

Abstract

The invention discloses a gas barrier preventing additive for vehicle navigation alcohol fuel. The technical problems of difficult starting, poor oil supply and vehicle shaking caused by high vapor pressure of existing alcohol navigation alcohol fuel during use of automobiles are solved. The gas barrier preventing additive comprises two or above of the following components: in parts by weight, 10-30 parts of trimethylcyclohexanone, 15-20 parts of rosin water, 5-10 parts of dibutyl ether, 0.5-5 parts of isopropyl ether, 10-15 parts of morpholine, 1-8 parts of octanal and 5-20 parts of petroleumether. Through addition of the gas barrier preventing additive, original self-association of methanol and original performance of methanol can be protected, the high vapor pressure of the navigationalcohol fuel can be avoided, and safety and reliability and smoothness of an oil passage during storage and use can be promoted.

Description

technical field [0001] The invention relates to an anti-gas blocking additive for aviation alcohol fuel for vehicles, which is added to aviation alcohol fuel to avoid higher vapor pressure of aviation alcohol fuel. The invention also relates to a preparation method of the aviation alcohol fuel anti-gas barrier additive. Background technique [0002] With the rapid development of the automobile industry, the world is facing more serious problems such as oil resource shortage and environmental pollution. Therefore, vigorously developing economical, energy-saving and environmentally friendly alternative energy has become a significant and long-term strategic consideration. Methanol gasoline has become an ideal gasoline substitute due to its wide source, low production cost, good combustion effect, and less environmental pollution. my country is a large coal country, and the technology of extracting methanol from coal is also very mature, with low cost, and can be used as a cle...
