- 気泡塔型反応器内で、反応液中に分散する固体触媒の存在下に、メタノールを一酸化炭素でカルボニル化して酢酸を製造する方法であって、
反応器下部よりメタノールを導入するとともに一酸化炭素含有ガスを反応液中に吹き込む一方、反応器上部において未反応の一酸化炭素を含む気相成分を反応液から分離し、
該気相成分をオフガスとして反応器頂部より抜き出し、これに対してガス洗浄操作を行う一方、気相成分を分離した後の反応液は、固体触媒を沈降させた後、固体触媒を含まない上澄部分を粗酢酸として抜き出し、残部を固体触媒とともに反応器下部に循環流入させることを含んでなり、
ガス洗浄操作後のオフガスの20〜99%を圧縮し、反応器下部より反応液中に吹き込む一酸化炭素含有ガスの一部として再利用し、かつ、
該反応器内の気相中一酸化炭素の分圧を1.0〜2.5MPaとし、全反応圧を3.0〜4.5MPaとし、該反応器からの一酸化炭素の排出率を理論反応量の3%以上とし、該反応器内におけるガス空塔速度を2cm/秒以上とすることを特徴とする方法。 - 該固体触媒がロジウム含有固体樹脂触媒である請求項1記載の方法。
- 該反応器内の固体触媒の濃度が反応容積あたり50kg/m3以上である請求項2記載の方法。
- 高圧条件で使用でき、比較的小揚程なリサイクルコンプレッサーで、該ガス洗浄操作後のオフガスの一部を圧縮する請求項1〜3のいずれか記載の方法。
