Brazil burns significant amounts of ethanol biofuel. Methanol, ethanol, and propanol are miscible in water. It is insoluble in methanol, ethanol, and water. Breweries and biofuel plants employ two methods for measuring ethanol concentration. Maize is also used in making ethanol and other biofuels. Maize is increasingly used as a feedstock for the production of ethanol fuel. This included development of alternative sources of energy such as wind, ethanol, and biofuels. Benzalkonium chloride is readily soluble in ethanol and acetone. The dominant ethanol feedstock in warmer regions is sugarcane. Growing feedstocks consumes most of the water associated with ethanol production. Sugars for ethanol fermentation can be obtained from cellulose. It may become a valuable asset for the production of cellulosic ethanol. Legislation imposes a 10% cap on the concentration of fuel ethanol blends. Isopropyl alcohol is miscible in water, ethanol, ether, and chloroform. Fermentation produces slightly less than ethanol by weight.
