An unsaturated nitrile. Its official name is 2-propenenitrile, but it is commonly called acrylonitrile. It is also called vinyl cyanide, cyanoethylene, and acrylic acid nitrile. A liquid with a unique sweet smell. Industrially, it is synthesized by the Sohio process using ammoxidation of propylene (CH 2 =CH-CH 3 ) , ammonia (NH 3 ) , and oxygen (air) with a molybdenum catalyst. It further reacts with ammonia and oxygen to produce acetonitrile (CH 3 CN) as a by-product. CH 2 =CH-CH 3 +NH 3 +3/2O 2 [Rikuhei Tani [Reference items] | | | | | | | [Supplementary materials] |Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
不飽和ニトリルの一つ。正式には2-プロペンニトリルというが、一般的にはアクリロニトリルといわれている。シアン化ビニル、シアノエチレン、アクリル酸ニトリルともいう。 独特の甘いにおいのする液体。工業的には、モリブデン系触媒を用いてプロピレンCH2=CH-CH3、アンモニアNH3、酸素(空気)を原料とするアンモ酸化によるソハイオ法で合成されている。アンモニア、酸素とさらに反応してアセトニトリルCH3CNを副生する。 CH2=CH-CH3+NH3+3/2O2 [谷利陸平] [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 |
