Alcohol from Broken Rice

Ethanol (ethyl alcohol CH3 – CH2 – OH) is one of the chemical compounds (alcohol)containing molecules with a guaranteed group (OH) per atom. Fermented alcohol is produced by the fermentation of agricultural products such as sugarcane, corn, and manure. Most of the fermentation produced worldwide comes from alcohol cane, mainly in Brazil. Within the United States, fermentation alcohol is made from corn. Ethanol is used as a high octane fuel in vehicles. More than 4 million cars in Brazil run on pure, hydrated ethanol, and all gasoline in the country is mixed with anhydrous ethanol (20–26% ethanol), as a result of the government’s plan to produce ethanol from cane in the 1970s. In the United States, a similar program has been launched and the number of vehicles using ethanol is increasing. Ethanol produces an excellent motor fuel: it contains a motor octane number, which is higher than the amount of gasoline and the vapor pressure is lower than that of gasoline, resulting in lower evaporation. The combustibility of ethanol in air is lower than that of gasoline, which reduces the number and severity of motor vehicle accidents.
