5%- 10% of n-octane, 0/5%-20% of iso-toluene/kloc, 25%-30% of n-butanol and 0/0%-35% of methyl cyclopentane/kloc. Methanol is prepared by replacing raw materials with methanol, 70-88% diesel oil and 2-5% methanol diesel oil additive according to the volume ratio 10-25%.
The main composition of crude oil is about 5? 12 chain hydrocarbons or aromatic hydrocarbons are mainly nonpolar, while the polarity of methanol is converted, so the solubility of direct mixing is not good, and the density difference can be reached. Coupling can be assisted by using small molecular esters such as plasma or acetic acid.
Methanol (anhydrous CH4O) is the simplest saturated monohydric alcohol, with CAS number of 67-56- 1, 170082- 17-4, molecular weight of 32.04 and boiling point of 64.7℃.
Extended data:
Chemical treatment mainly uses alkali to destroy impurities that are difficult to separate during distillation and adjust pH value. Distillation mainly removes volatile components such as dimethyl ether, almost non-volatile ethanol, higher alcohols and water. The purity after crude distillation can usually reach 98% or higher.
The concentration of industrial methanol is reduced to 0.0 1% or lower by distillation. Treat with sodium iodate and remove the screw. Refining to obtain pure methanol.
At room temperature, gasoline is a colorless to yellowish flowable liquid. Insoluble in water, flammable. When the distillation range is 30°C to 220°C and the air content is 74 to 123g/m3, it will catch fire. The calorific value is about 44000 kJ/kg (the calorific value of fuel is 65,438+0 kg of fuel converted after complete combustion).
