An aromatic hydrocarbon. Also known as isopropylbenzene or cumol. It is derived from cumin oil, an essential oil obtained from the caraway plant , Cuminum cyminum . Industrially, it is produced by subjecting benzene to the Friedel-Crafts reaction with propylene. It is insoluble in water, but soluble in various organic solvents. It was once used as a blending agent for high-octane gasoline. It is also a raw material for the synthesis of phenol and acetone by the cumene process. It is also used in the synthesis of acetophenone and α-methylstyrene.

芳香族炭化水素の一つ。イソプロピルベンゼン、クモールともいう。ヒメウイキョウCuminum cyminumから得られる精油であるクミン油から得られるのでこの名がある。工業的にはベンゼンにプロピレンをフリーデル‐クラフツ反応させて製造される。水には不溶であるが、各種有機溶剤には溶ける。かつては高オクタンガソリンの配合剤としても用いられた。またクメン法によるフェノールとアセトン製造の合成原料。また、アセトフェノンやα(アルファ)-メチルスチレンの合成に用いられる。 [向井利夫] [参照項目] | [補完資料] |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
