NOVELTY - High stability and low volatile methanol gasoline comprises 10-15 pts. wt. methanol, 3-5 pts. wt. modified oxide graphene and 35-65 pts. wt. gasoline. USE - Used as high stability and low volatile methanol gasoline. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing high stability and low volatile methanol gasoline, comprising (i) mixing uniformly graphene oxide, trimethylolpropane triglycidyl ether, tetrabutylammonium bromide and N, N-dimethylformamide at a mass ratio of 10:8:1:20-10:10:1:25 in a nitrogen atmosphere, stirring at 80-90°C under the stirring condition of 800-1000 revolutions/minute for 2-3 hours and at 40-50°C under 1-2 kPa for 8-10 hours to obtain pre-modified graphene oxide; (ii) mixing pre-modified graphene oxide, nitrilotriacetic acid, tetrabutylammonium bromide and N,N-dimethylformamide in a mass ratio of 5:5:1:20-5:7:1:25 in nitrogen atmosphere, stirring at 70-80°C under the stirring condition of 500-700 revolutions/minute for 2-3 hours, adding trimethylolpropane triglycidyl ether with 1-1.2 times the mass of pre-modified graphene oxide and continuously stirring for 2-3 hours, adding glycolic acid with 1-1.2 times the mass of pre-modified graphene oxide, stirring and reacting for 2-3 hours, allowing to stand at 40-50°C under 1-2 kPa for 8-10 hours, adding ethyl acetate with 3-5 times the mass of pre-modified graphene oxide, and washing with 5-6% sodium bicarbonate solution, 15-20% sodium chloride solution and deionized water for 3-5 times, washing, drying solution with anhydrous magnesium sulfate and filtering to obtain modified graphene oxide; and (iii) uniformly mixing methanol, modified graphene oxide, and gasoline at a mass ratio of 10:3:40-15:5:60.
