The production process.1. the synthesis.The synthesis of ethanol can be synthesized from ethylene (C2H4) by two methods.– The Directory Migration high ethylene by the reaction of ethylene with water vapor at the same concentrations. At a pressure of 5-8 Mecca plasma temperature of Scala 250-300 degrees Celsius. Using the catalyst is phosphoric acid, Millard-silica gel and tungsten oxide-silica gel, making the alcohol concentration has 10-25% of the equation.C2H4 + H2O = CH3CH2OH2CH3CH2OH = (CH3CH2)2O + H2O-In the directory High immigration ethylene by first Use pure ethylene handling 35-95% sulfuric acid the reaction with ethanol, make possible intensive lokwam cannot exceed 35% of the equation.C2H4 + H2SO4 = CH3CH2OSO3H2(C2H4) + H2SO4 = (CH3CH2O)2SO2Phase II reactions hydrogen sulfate in saethin 2 SIM Lite until ethanol.CH3CH2OSO3H + H2O = CH3CH2OH + H2SO4(CH3CH2O)2SO2 + H2O = 2(CH3CH2O) + H2SO4This method of synthesis can increase the concentration of ethanol. 50-60% by increasing the concentration of sulphuric all this. How to produce ethanol with this synthesis is currently not popular due to the high cost and are not worth the investment.2. microbial fermentation.The traditional method is commonly used in the production of ethanol demand is present because it is a low-cost. The process is complicated and can find the raw material production. These raw materials used include cassava, sugarcane, corn and molasses.To produce ethanol or ethyl alcohol, is a fermentation process using a yeast fermentation of alcohol production raw materials, starchy and sugar cellulose into sugars, single molecule and single molecule is a sugar alcohol, changes at concentrations of 10-15% under the vulnerable wireless air and brewing process to obtain pure alcohol.C6H12O6 + 2C2H5OH + 2CO2 + 2ATP = yeast.
