Molecular formula : CH3OH
CAS :
nature : also known as wood alcohol, wood intensive. The volatile flammable colorless transparent polar liquids, toxic, drink or its vapor can contact blinding. Pure ethanol smells slightly crude pungent smells bad. -93.9 ° C melting point. The boiling point of 65 ° C. The relative density of 0.7914. Refractive index of 1.3288. Viscosity (20 ° C) 0.5945mPa s. Flash point (open cup) 16 ° C Spontaneous point 473 ° C With water, alcohol, ether, acetone, benzene, solvents most immiscibility. Explosion range (20 ° C) 6.0% 36.5% (vol). Saturated with the hull of Alcohol can also be used for carbonylation, methylation reaction, together with zinc powder distillation break down into CO and H2O, and also with CaCl2, BaO, MgCl< SUB>2, CHSO4, AlCl3 etc. can be dissolved in methanol crystalline complexes, such as CaCl2 4CHk UB>3OH. Methanol was first proposed by the dry distillation of timber obtained, the contemporary industrial to synthesis gas (CO + H2) as raw materials, to a certain temperature, pressure and the presence of synthetic catalysts. With the use of different catalyst, a high-pressure synthesis method and medium voltage and low-voltage sector. Methanol is one of the basic organic materials, a wide range of uses. Preparation formaldehyde mainly used in organic synthesis and Industry for methylation agents and solvents, is oxygenated gasoline component methyl tert-butyl ether (MTBE), the precursor can be added to gasoline or separately as vehicle fuel, or some pesticide manufacturers, pharmaceutical raw materials.
