TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: Alternatively, preparing alcohol ether fuel comprises: (a) preparing mixing liquid of methanol, ethanol and gasoline; (b) oscillating and mixing; (c) adding petroleum microorganism leaven and methyl tertiary butyl ether; (d) adding grease containing latent solvent synergistic agent; (e) hot mixing and (f) standing by; (a) preparing mixing liquid of methanol, ethanol and gasoline: mixing the methanol added with additive, the ethanol added with dimethyl ether and nitrobenzene and the gasoline added with carotene in a container to prepare mixing liquid of methanol, ethanol and gasoline, where ratio of methanol to ethanol to gasoline is at (150-650)-(50-250)-(50-450) by weight; ratio of methanol to additive is at 1000-(0.5-3) by weight and the additive contains xylene, butanol, methyl ester, acetic acid, cyclohexanone and isopropanol; ratio of ethanol to dimethyl ether to nitrobenzene is at 100-(10-35)-(1-3) by weight; and ratio of gasoline to carotene is at 1000:(0.0005-0.005) by weight; (b) oscillating and mixing: oscillating and mixing the mixing liquid of methanol, ethanol and gasoline prepared by (a) at normal temperature and under normal pressure by frequency of 160-300000 Hz for 20-100 minutes; (c) adding petroleum microorganism leaven and methyl tertiary butyl ether: synchronously adding petroleum microorganism leaven and methyl tertiary butyl ether in mixing liquid of methanol, ethanol and gasoline oscillated and mixed by (b), where ratio of mixing liquid to petroleum microorganism leaven is at 1000-(0.01-0.75) by weight and ratio of mixing liquid to methyl tertiary butyl ether is at 1000-(10-30) by weight; (d) adding grease containing latent solvent synergistic agent: adding grease containing latent solvent synergistic agent in the mixing liquid in 15-60 seconds after (c), where ratio of mixing liquid to grease is at 1000:(2-20) by weight and ratio of grease to latent solvent synergistic agent is at 1000 at (100-800) by weight; the latent solvent synergistic agent contains butanol, acetone, xylene and 16 sodium alkyl benzene sulfonate; (e) hot mixing: mixing the mixing liquid prepared by (d) for 0.3-1.5 seconds at 40-205 degrees C under normal pressure; and (f) standing by: standing the solution for 10-50 minutes to obtain the alcohol ether fuel.
