absolute alcohol



absolute alcohol the common name for pure ethanol, i.e. ethanol that has been freed of water. It may contain small amounts of benzene that have been added to aid in removing water. Substances may be added to absolute alcohol to render it unfit for human consumption and hence free of excise duty: industrial spirit contains 5% v/v methanol, while methylated spirit also contains pyridine, petroleum oil, and methyl violet dye, and surgical spirit also contains castor oil, diethyl phthalate, and methyl salicylate.
