Abstract

The invention relates to a methanol gasoline with high stability, which is prepared from the following raw materials in volume: 70-88 percent of gasoline, 5-15 percent of methanol, 2-5 percent of diethylamine, 2-5 percent of toluene, 1-5 percent of tween 80, 2-5 percent of dodecyl sodium sulfate; the methanol gasoline is prepared by the following steps: adding the tween 80 and the dodecyl sodium sulfate in the gasoline and evenly mixing to obtain mixed solution for standby; and evenly mixing the methanol, the diethylamine and the toluene in a high-frequency electromagnetic processor for magnetic processing and immediately adding the processed solution in the mixed solution, evenly mixing to obtain the methanol gasoline. The methanol gasoline with high stability can ensure that the methanol and the gasoline are organically fused, has good stability, does not layer after long-term storage and can realize the commercialized production of the methanol gasoline.

Description

A kind of methanol gasoline with high stability

Technical field

The invention discloses a kind of gasoline that is added with methyl alcohol, particularly a kind of methanol gasoline with high stability.

Background technology

At present, China adds about 10% ethanol in order to reduce the consumption to gasoline in gasoline, be called ethanol petrol.But, cause ethanol petrol not have cost advantage because the alcoholic acid manufacturing cost is higher.

Now also there are some in gasoline, to add the report of methyl alcohol; A kind of methanol gasoline clean fuel for petrol engine is disclosed like Chinese patent 01138648.7; Be made up of methyl alcohol, gasoline and solubility promoter, the volume percent that methyl alcohol and solubility promoter account for the clean fuel TV respectively is 5～30% and 0.5～4%.This clean fuel can be not stratified when envrionment temperature reaches or be lower than-15 ℃, thereby have package stability preferably.But above-mentioned clean fuel is under the normal temperature or the condition of high temperature, and package stability is relatively poor, does not reach widely used security.

Summary of the invention

The present invention provides a kind of good stability in order to overcome the deficiency of above technology, methanol gasoline with high stability that can long storage.

The present invention realizes through following scheme:

A kind of methanol gasoline with high stability is characterized in that adopting following steps to process:

(1) raw material is by volume measured proportioning and is: gasoline 70-88%, methyl alcohol 5-15%, diethylamine 2-5%, toluene 2-5%, tween 80 1-5%, sodium laurylsulfonate 2-5%;

(2) earlier tween 80 and sodium laurylsulfonate are added in the gasoline, mix, it is subsequent use to get mixed solution;

(3) with methyl alcohol, diethylamine and toluene mix, and put into the high-frequency electromagnetic treater and magnetize processing 1-2 hour, and the frequency of high-frequency electromagnetic treater is 1000-5000Hz; Magnetization adds in the mixed solution of step (2) after handling immediately, stirs, and gets final product.

Methanol gasoline with high stability of the present invention through adding a certain amount of material that attaches, is handled through electronic curing again, can make methyl alcohol and gasoline organically fused, and stability is good, and long storage is not stratified, realizes the commercialization production of methanol gasoline.
