This method involves oxidizing ammonia NH3 to produce nitric acid HNO3 . Ammonia is mixed with air or oxygen and reacted with the help of a catalyst at a high temperature of about 900 ° C to obtain nitric oxide NO, which is then further oxidized to nitrogen dioxide NO2 after cooling. This nitrogen dioxide is absorbed in water to produce nitric acid. 4NH 3 +5O 2 -→4NO+6H 2 O [Ginya Adachi] [Reference] |Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
アンモニアNH3を酸化して硝酸HNO3を製造する方法。アンモニアを空気または酸素と混合し、900℃程度の高温で触媒の助けを借りて反応させ、一酸化窒素NOを得、冷却後、これをさらに酸化して二酸化窒素NO2にする。この二酸化窒素を水に吸収させて硝酸を製造する。 4NH3+5O2―→4NO+6H2O [足立吟也] [参照項目] |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 |
