isopropanol,

isopropyl alcohol,

2-propanol

(ī'səprō`pənōl, ī'səprō`pĭl), (CH₃)₂CHOH, a colorless liquid that is miscible with water. It melts at −89°C; and boils at 82.3°C;. It is poisonous if taken internally. It is a major component of rubbing alcohols. Isopropanol is a secondary alcoholalcohol,
any of a class of organic compounds with the general formula R-OH, where R represents an alkyl group made up of carbon and hydrogen in various proportions and -OH represents one or more hydroxyl groups.

Isopropanol is made commercially by dissolving propylene gas in sulfuric acid and then hydrolyzing the sulfate ester that is formed; the propylene is a byproduct of petroleum refining. Isopropanol was formerly obtained largely by catalytic reduction of acetoneacetone
, dimethyl ketone
, or 2-propanone
, CH₃COCH₃, colorless, flammable liquid. Acetone melts at −94.8°C; and boils at 56.2°C;. It is the simplest aliphatic ketone.
