It is an isomer of cyanic acid HOCN. Its chemical formula is HONC and its formula weight is 43.0. Mercury salts and silver salts have been known for a long time. If the salt is decomposed with a strong acid, the free acid is obtained as an aqueous solution, but it is extremely unstable and polymerizes quickly. It is difficult to obtain a pure form. It smells like hydrogen cyanide and is toxic. Silver salts and mercury salts explode violently when heated, impacted, or rubbed.

シアン酸HOCNの異性体の一つ。化学式HONC、式量43.0。水銀塩や銀塩は古くから知られている。塩を強酸で分解すれば水溶液として遊離の酸が得られるが、きわめて不安定で、すぐに重合する。純粋なものは得られにくい。シアン化水素のようなにおいがして有毒。銀塩、水銀塩などが加熱、衝撃、摩擦などによって激しく爆発する。 [守永健一・中原勝儼] [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 |
