Characteristics: A clear, colorless, mobile liquid, having a slight characteristic odor and a burning taste. It is miscible with water, with ether and with chloroform. It boils at about 78°C and is flammable. Its refractive index at 20°C is about 1.364.
Ethanol content: Not less than 94.9% by volume (92.3% by weight)
Acidity, as acetic acid: Not more than 0.003% (30 ppm*)
Alkalinity, as NH3: Not more than 3 mg/kg (3 ppm*)
Fusel oil content: Passes odor test on evaporation residue
Heavy metals, as lead: Not more than 1 mg/kg (1 ppm*)
Ketones and iso-propanol: Passes mercuric sulfate test
Methanol: Passes test with chromotropic acid
Non-volatile residue: Not more than 0.003% (30 ppm*)
Solubility in water: Passes dilution test
Substances darkened by sulfuric acid: Passes test
Substances reducing permanganate: Passes test (more than 5 minutes at 15°C)
The "ppm" (parts per million) figures are not included in the original standard, but are added to facilitate comparisons with other standard specifications.
