It is added sulfuric acid agitating and heating reflux dewatering 2~3 hours at~35 DEG C, is cooled to room temperature；
(2) dimethoxym ethane, glycol ether, normal propyl alcohol, isopentane are continuously added, 3~4h is stirred at 45~60 DEG C, is cooled to
After room temperature, it is washed till pH to 8-9 with 10~15% aqueous sodium carbonate, then be washed till neutrality with saturated sodium-chloride water solution, separated
Aqueous solution was filtered to remove organic addition desiccant dryness 14~16 hours of aqueous solution desiccant, and obtained additive；
(3) methanol and obtained additive are mixed at 25~35 DEG C, stirs evenly, is cooled to room temperature；
(4) substance obtained in step (3) is uniformly mixed with 60~65% gasoline, obtains gasoline.
Preferably, a kind of preparation method of methanol gasoline in step (1), heats at 30 DEG C.
Specifically, a kind of preparation method of methanol gasoline, step stirs 3.5h at 55 DEG C in (2), after being cooled to room temperature,
PH is washed till to 8 with 15% aqueous sodium carbonate.
Preferably, a kind of preparation method of methanol gasoline, by methanol and obtained additive at 25~35 DEG C in step (3)
Lower mixing, stirs evenly, is cooled to room temperature.
Wherein, additive includes the component of following parts by weight: 21~26 parts of methanol, 11~14 parts of glycerine, isobutanol
18~24 parts, 8~14 parts of isopentane, 13~24 parts of toluene, 10~15 parts of dimethylbenzene, 21~26 parts of dimethoxym ethane, glycol ether 13
