Description
1.5mの内径及び18mの内のり高さを有するヒドロホルミル化反応器を完全に空にし、引き続き高温水を何度か注入し、そして再び空にすることで、有機材料の残分を実質的に除去した。反応器に、コバルト64g/lを含みかつ20℃の温度を有する硝酸水溶液10m3(65gのHNO3/l)を注入した。引き続き、硝酸を反応器の底部でポンプを使って抜き出し、かつ上部で再び反応器中に加える。このようにして、約8m3/hでポンプ循環させた。
1mの内径及び18mの内のり高さを有するヒドロホルミル化反応器を完全に空にし、引き続き高温水を何度か注入し、そして再び空にすることで、有機材料の残分を実質的に除去した。反応器に、コバルト29g/lを含みかつ20℃の温度を有する硝酸水溶液20m3(161gのHNO3/l)を注入し、その際、硝酸の一部が後反応器中に溢流した。引き続き、硝酸を後反応器の底部でポンプを使って抜き出し、反応器の下部に返送した。このようにして、約8m3/hでポンプ循環させた。
1.5mの内径及び18mの内のり高さを有するヒドロホルミル化反応器を、20%の硝酸10m3を用いることによって洗浄した。洗浄が首尾よく行われていることをモニタリングするために、反応器中での内部循環時間を放射性トレーサー(radioaktive Stossmarkierung)によって測定した。指示薬として、ナトリウムの同位体24Naを使用した。
