The straight chain isomer with the alcohol at an … See more 2-methyl-2-butanol is a central nervous system depressant with a similar effect upon ingestion to ethanol. Case reports have been documented demonstrating its potential for abuse. See more Since the 1950s, most butanol in the United States is produced commercially from fossil fuels. The most common process starts with propene (propylene), which is put through a hydroformylation reaction to form butanal, which is then reduced with See more Butanol exhibits a low order of toxicity in single dose experiments with laboratory animals and is considered safe enough for use in cosmetics.
