Description
メタクロレインの調製
長さ29インチ、内径0.1315インチのスタティックミキサーを反応器として使用した。ジメチルアミン、酢酸、および水を触媒混合容器内で混合し、そこからの出口流量は、550g/時間であり、4.5重量%のジメチルアミンと、ストリームのpHを5.5に維持するのに十分な量の酢酸と、を含有した。10~15%のメタノールも含有する水中のプロピオンアルデヒドおよび37重量%のホルムアルデヒド溶液(1:1のプロピオンアルデヒド:ホルムアルデヒドのモル比)を含む、ストリームを、1575g/時間の総流量で、水性触媒溶液と混合し、反応器に添加し、それを、160℃に加熱し、900psigに維持した。水中に8重量%の4-ヒドロキシ-TEMPOを含有する阻害剤溶液を、20g/時間の流量で反応器に添加した。反応器の出口を20℃まで冷却し、1気圧に減圧し、5℃の内部温度および1気圧の圧力である相分離器に送った。相分離器からの有機および水流量は、それぞれ1220g/時間および1470g/時間であった。有機相には、メタクロレインが93重量%含有され、水相には、水が84重量%含有されていた。有機相は、9つのトレイを備えたストリッピング塔に送られ、メタノール中に8重量%の4-ヒドロキシ-TEMPOを含有する阻害剤溶液を、6g/時間の流量でストリッピング塔の凝縮器に添加した。ストリッピング塔からのオーバーヘッド蒸気は凝縮され、相分離器に戻りリサイクルされた。ストリッピング塔からの底部ストリームは、675g/時間の流量で、22個のトレイを備えた蒸留塔に送られ、蒸留物は、下流の酸化エステル化プロセスに送られ、底部ストリームは、廃棄に送られた。メタノール中に8重量%の4-ヒドロキシ-TEMPOを含有する阻害剤溶液を、10g/時間の流量で蒸留塔の凝縮器に添加した。蒸留物は、645g/時間の流量で、97重量%のメタクロレイン、0.9重量%の水、1.6重量%のメタノール、および0.5重量%未満の組み合わされた望ましくない不純物(例えば、酢酸、プロピオン酸、メタクロレイン二量体、および2-メチル-2-ペンテナール)からなる。水相は、30個のトレイを備える蒸留塔に送られ、そこからの蒸留物流量は220g/時間であり、56重量%のメタノールと、44重量%のメタクロレインと、0.1重量%の水とからなり、それは、下流の酸化エステル化プロセスに送られた。メタノール中に8重量%の4-ヒドロキシ-TEMPOを含有する阻害剤溶液を、16g/時間の流量で蒸留塔の凝縮器に添加した。蒸留塔からのサイドドロー流量は、主に水と0.9重量%のメタノールを含む735g/時間であった。メタノール中に8重量%の4-ヒドロキシ-TEMPOを含有する阻害剤溶液を、2g/時間の流量で蒸留塔のサイドドローレシーバに添加した。蒸留塔からの底部ストリームは、主に水と回収されたアミン酸触媒を含有した。蒸留塔からの底部ストリームの0.75の一部分は、触媒混合容器にリサイクルされた。
