If you support a cooking pot over the flame, you can boil a litre of water in about 16 minutes - no special equipment required! I tried a stainless steel egg cup and it worked fine. It is simple to use metho as a cooking fuel - simply place about 30 ml in a small metal container and light it. For comparison, the energy released during the combustion of propane and butane are about 50 kJ/g and 49 kJ/g respectively. The energy released from burning ethanol is approximately 30 kJ/g. It is commonly used as a denaturant for ethyl alcohol, and is miscible with water. It is poisonous and, if consumed, causes blindness, insanity, and eventual death. Methanol burns with a pale, non-luminous flame. Its boiling point is 64.6 deg C, and its melting point is -97 deg C. It is produced by the destructive distillation of wood, or by a synthetic process which involves reacting carbon monoxide with hydrogen gas. Methyl alcohol, or methanol, is also sometimes called wood spirit. When Ethanol is burnt in air, the results of combustion are carbon dioxide and water. Ethanol is used as an additive to car fuel and is burnt with liquid oxygen in some rocket engines. Uses include consumption in alcoholic beverages, a solvent, an anti-freeze solution, and a fuel. Its boiling point is 78.5 deg C, and its melting point is -117.3 deg C.Įthanol burns with a hot, pale-blue flame. It is a renewable energy source.Įthanol's formula is C 2H 5OH. The methyl alcohol is poisonous and is added to prevent the methylated spirits being used as cheap drinking alcohol.Įthyl alcohol, or ethanol, is produced by the fermentation of sugars, or from direct synthesis from ethylene. Methylated spirits ("metho") is a mixture of ethyl alcohol (95%) and methyl alcohol (%5).
