The History of Methyl alcohol

Methyl alcohol is a chemical with the formula CH3OH (often abbreviated MeOH). In their embalming process, the ancient Egyptians used a mixture of substances, including methanol, which they obtained from the pyrolysis of wood. Pure methanol, however, was first isolated in 1661 by Robert Boyle, when ...

The toxicity of 1-Butanol

1-Butanol is readily absorbed through the intestinal tract and lungs, and also to some extent through the skin. It is metabolized completely in vertebrates in a manner similar to ethanol: alcohol dehydrogenase coverts 1-Butanol to butyraldehyde; this is then converted to butyric acid by aldehyde deh...
