![]() ![]() From 25–27 December 1926, which was roughly at the midpoint of the "Noble Experiment" of nationwide alcohol prohibition, 31 people in New York City alone died of methanol poisoning. For instance, during the Prohibition in the United States, federal law required methanol in domestically manufactured industrial alcohols. This can result in blindness or death if it contains methanol. See also: List of methanol poisoning incidents and Harm reduction § Alcoholĭespite its poisonous content, denatured alcohol is sometimes consumed as a surrogate alcohol. If pure ethanol were made cheaply available for fuel, solvents, or medicinal purposes, it would likely be enjoyed as a drink by many people without payment of alcoholic beverage taxes. As denatured alcohol is sold without the often heavy taxes on alcohol suitable for consumption, it is a cheaper solution for most uses that do not involve drinking. ĭenatured alcohol has no advantages for any purpose over normal ethanol it is a public policy compromise. In molecular biology, denatured ethanol should not be used for the precipitation of nucleic acids, since the additives may interfere with downstream applications. Pure ethanol is required for food and beverage applications and certain chemical reactions where the denaturant would interfere. Denatured alcohol is used identically to ethanol itself except for applications that involve fuel, surgical and laboratory stock. Its composition is tightly defined by government regulations in countries that tax alcoholic beverages. In order to avoid paying beverage taxes on alcohol that is not meant to be consumed, the alcohol is usually "denatured", or treated with added chemicals to make it unpalatable. In many countries, sales of alcoholic beverages are heavily taxed for revenue and public health policy purposes (see Pigovian tax). For many of these solutions, it is intentionally difficult to separate the components. Rather, the ethanol is mixed with other chemicals to form a foul-tasting, often toxic, solution. ![]() ĭenaturing alcohol does not alter the ethanol molecule ( chemically or structurally), unlike denaturation in biochemistry. ĭenatured alcohol blends average 60 to 90% ethanol. Other common additives include isopropyl alcohol, acetone, methyl ethyl ketone, and methyl isobutyl ketone. The main additive usually is 10% methanol (methyl alcohol), hence the name methylated spirits. Because of the diversity of industrial uses for denatured alcohol, hundreds of additives and denaturing methods have been used. Pyridine and methanol, each and together, make denatured alcohol poisonous and denatonium makes it bitter.ĭenatured alcohol is used as a solvent and as fuel for alcohol burners and camping stoves. It is sometimes dyed so that it can be identified visually. The human health effects of these chemicals are listed in this document.Ethanol with additives to discourage recreational consumptionġ US gallon or 3.785 litres of denatured alcohol in a metal containerĭenatured alcohol (called methyl hydrate in Canada methylated spirits, metho, or meths in Australia, Ireland, New Zealand, South Africa, and the United Kingdom wood spirit and denatured rectified spirit) is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption.
