Abstract
The invention discloses a method for preparing methanol gasoline, which comprises the following steps of: mixing isoamyl alcohol and amyl ether in a certain ratio with industrial methanol to obtain denatured methanol for later use; selecting fatty alcohol-polyoxyethylene ether, dimethyl carbonate, ethyl oleate and tertiary butyl phenol according to a ratio and adding the materials into a container sequentially to stir for 20 to 30 minutes to prepare a methanol gasoline modifying agent for later use; adding 70 percent of the gasoline into 26 percent of the denatured methanol to stir completely and uniformly; and then adding 4 percent of the gasoline modifying agent into the container, mixing the mixture fully, and finally obtaining the methanol gasoline finished products. The methanol gasoline product has the advantages of no demixing, high stability, no corrosion, no swelling, no emulsification, strong explosive force, convenient use, readily available raw materials and low manufacturing cost.
Description
Technical field
The present invention relates to a kind of manufacture method of environment-friendly methanol gasoline, can effectively improve the stability of methanol gasoline.
Background technology
The methanol gasoline of Xiao Shouing is all directly blent basically in the market.Generally do not take special process to handle, so there are a lot of problems.As emulsification, swelling, layering, burn into vapour lock, be short of power.
Summary of the invention
In view of above-mentioned present situation, the purpose of this invention is to provide a kind of manufacture method of environment-friendly methanol gasoline, can operate at normal temperatures and pressures, industrial methanol is carried out mixing with gasoline after the sex change, add properties-correcting agent again, make it have the satisfactory stability performance and explosive power strong, significantly reduce carbon emission.
Preparation method's step of the present invention is:
1, will select 0 for use, 1%-0,5% primary isoamyl alcohol and 0,2%-0,5% amyl ether is put in the industrial methanol of getting ready and mixes, and it is standby to make it to become denatured methyl alcohol;
2, select for use following each raw material weight per-cent to prepare gasoline modified dose:
Fatty alcohol-polyoxyethylene ether 54-84%;
Methylcarbonate 10-30%;
Ethyl oleate 5-10%;
P-tert-butylphenol 1-6%.
3, with each raw material of step 2 by proportioning, be docile and obedient preface and add and to stir 20-30 minute in the container to evenly, it is standby promptly to make methanol gasoline properties-correcting agent;
4,70% gasoline is joined in 26% the denatured methyl alcohol and stir, and then add 4% gasoline modified dose, make it thorough mixing and be second methanol gasoline finished product.
According to characteristics of the present invention, prepare gasoline modified dose by following each raw material weight per-cent:
Fatty alcohol-polyoxyethylene ether 54-84%;
Methylcarbonate 10-30%;
Ethyl oleate 5-10%;
P-tert-butylphenol 1-6%.
Further, gasoline modified dose optimum weight per-cent of preparation is:
Fatty alcohol-polyoxyethylene ether 73%;
Methylcarbonate 17%;
Ethyl oleate 7%;
P-tert-butylphenol 3%.
In the present invention, methanol gasoline comprises following weight percentages and makes:
Denatured methyl alcohol 10-40%
Gasoline 58-84%
Properties-correcting agent 2---6%
Further, the preferred weight percent of each raw material of preparation methanol gasoline is:
Denatured methyl alcohol 15-30%
Gasoline 67-80%
Properties-correcting agent 3--5%
Further, the optimum weight proportioning of each raw material of preparation methanol gasoline is:
Denatured methyl alcohol 23%
Gasoline 73%
Properties-correcting agent 4%
The effect that the present invention had is: 1, use this product environment-friendly methanol gasoline, not stratified good stability, no burn into do not have swelling, strong, the power of floatingization, explosive power does not subtract.2, this agent wide accommodation all is suitable for as light oil, diesel oil, solvent oil.3, quality reaches " Vehicular methanol petrol " standard, need not improve engine, can directly use.4, when configuration depressed operation at normal temperature, technology is simple, easy to operate.5, raw material is easy to get, and cost is low.
