Methanol diesel oil and preparation method thereof

The invention provides methanol diesel oil, which is prepared from the following ingredients in percentage by weight: 60 to 85 percent of diesel oil, 5 to 30 percent of methyl alcohol, 1 to 5 percentof water, 1 to 10 percent of modifying agents and 0.01 to 0.03 percent of KBr. According to a preparation method, the diesel, the methyl alcohol, the water, the modifying agents and the KBr accordingto the recipe quantity are uniformly mixed; the materials are put under the ultrasonic waves being 1 to 10kHz to be vibrated for 3 to 10s to obtain a finished product. The prepared methanol diesel oilhas the advantages that the storage stability is high; the water resistant capability is high; the flash point is high; the cetane number is high; the low-temperature starting performance is good. 本发明提供了种甲醇柴油，各组分所占的重量百分比为：柴油60～85％、甲醇5～30％、水1～5％、改性剂1～10％、KBr 0.01～0.03％。其制备方法为将配方量的柴油、甲醇、水、改性剂和KBr混匀，置于1～10KHz超声波下振荡3～10s，即得。本发明制得的甲醇柴油具有储存稳定性好，抗水能力强，闪点高，十六烷值高，低温启动性能良好的优点。
