Also called methanol or wood alcohol. Chemical formula: CH 3 OH. Has an odor similar to ethyl alcohol. Poisonous, with 8-20 g causing blindness and 30-50 g causing death. Colorless, volatile, flammable liquid. Boiling point: 64°C. Produced industrially from carbon monoxide and hydrogen by high-pressure contact. The simplest molecule among alcohol homologues. When oxidized, it becomes formaldehyde, and when further oxidized, it breaks down into formic acid, and then into carbon dioxide and water. Raw material for organic synthesis (methylation reaction). Used as an analytical reagent, solvent, and fuel, and as a denaturing agent for ethyl alcohol.

メタノール,木精ともいう。化学式 CH3OH 。エチルアルコールに似た匂いを有する。有毒で,8~20gで失明,30~50gで死にいたる。無色揮発性,可燃性液体。沸点 64℃。一酸化炭素と水素から高圧接触法によって工業生産される。アルコール同族体で最も簡単な分子である。酸化するとホルムアルデヒドとなり,さらに強く酸化するとギ酸を経て,二酸化炭素と水にまで分解する。有機合成 (メチル化反応) の原料。分析用試薬,溶媒,燃料として用いられ,エチルアルコールの変性剤としても用いられる。
