Abstract

The invention discloses an M15 methanol gasoline vapor pressure stabilizer, which is prepared from 18.0-31.0% of N-(3-aminopropyl)-N-methyl tert-butyl carbamate, 15.0-29.5% of 2-dimethylamino-2-methyl-1-propanol, 15.0-24.5% of 6-methyl-3,5-heptadiene-2-ketone, 13.0-24.0% of diethyl tert-butyl hosphonoacetate, 10.0-20.5% of 2,2,5,5-tetramethyl tetrahydrofuran, and 9.0-19.5% of 2,3-dimethylhexane in a mixing manner. The vapor pressure stabilizer disclosed by the invention is significant in effect of reducing the vapor pressure of the M15 methanol gasoline; 0.2-0.5% of vapor pressure stabilizer is added to common M15 methanol gasoline, so that the vapor pressure of the methanol gasoline accords with the requirements of GB17930-2013 'motor gasoline'.

Description

technical field [0001] The invention belongs to the technical field of methanol replacing vehicle fuel, and relates to an additive for M15 methanol gasoline, in particular to an M15 methanol gasoline vapor pressure stabilizer. Background technique [0002] As the world's oil resources become increasingly scarce and air pollution becomes increasingly serious, the energy crisis has become a bottleneck restricting economic development, and new alternative fuels have attracted the attention of all parties. my country's dependence on foreign oil has exceeded 53%, and energy and environmental issues restrict the rapid development of my country's economy. my country is a country that is poor in oil and gas but relatively rich in coal. It is entirely feasible to replace part of the oil with coal to produce methanol. Using methanol as a substitute fuel for internal combustion engines is an effective way to protect the environment and use energy rationally. According to the National ...
