Description
i)部分酸化触媒の存在下で、アルカンを酸素または酸素含有ガス、例えば空気と反応させて、少なくとも1種の不飽和カルボン酸およびある濃度の飽和カルボン酸を含む生成物を生じさせ;および
ii)飽和カルボン酸への部分酸化反応選択性を低下させるか、または飽和カルボン酸の少なくとも一部を破壊するか、変換するか、もしくは分離することにより、飽和カルボン酸の不純物濃度を低下させること:を含むプロセスにおいて、C3からC8アルカンの部分酸化に由来する飽和および不飽和カルボン酸の混合物中に存在する飽和カルボン酸の濃度を低下させる方法である。

MoV0.285Te0.21Nb0.17Pd0.01酸化物バルク組成(X線蛍光により測定)を有するバルク粉体混合金属酸化物(MMO)触媒を合成し、プレスして、14から20メッシュ粒子サイズの粒子にした。4ccの不活性カーボランダムパッキングと混合された4.43gのMMO触媒を含む長さ4cmの触媒床を、直径1.27cm、長さ1.16mのステンレス鋼プラグフロー管状リアクターに装填し、中心に置いた。リアクターチューブの残りの容積に不活性カーボランダムパッキングを装填した。

FeP1.7O5.8バルク組成(X線蛍光により測定)を有するバルク粉体リン酸鉄触媒を合成し、プレスして14〜20メッシュ粒子の粒子にした。

アルデヒドとのアルドール縮合反応により生成物AA流れからPAを除去する。
5000ppmのPA(NBP 141.1℃)、ならびに数重量パーセントの低沸点成分(例えば、酢酸;NBP 118.5℃)および数重量パーセントの高沸点成分(例えば、アクリルオキシプロピオン酸)を含有するAA(NBP 141.6℃)の流れを、不活性物質(例えば、セラミックRaschigリングまたはサドル)で充填された単純蒸留カラムの下部に供給する。目的は、等量のAAおよび低沸点物質を用いてオーバーヘッドでそれを蒸留することによりPAのレベルを約10倍減少させること、およびAAおよび高沸点物質をボトム生成物として回収することである。PA/AA相対揮発度を約1.01と仮定して、分離を行うために必要な最小パッキング高さは約800の理論段数に等しく、AA分離の目的は非現実的になる。
Rohm and Haas CompanyのAmberlyst(商標)15樹脂(スルホン酸官能性(4.9meq/g)を有する強酸性マクロ網状イオン交換樹脂)を硝酸銀水溶液で処理して、樹脂を酸形態から銀イオン形態に変換する。変換された樹脂を水ですすぎ、真空オーブン中で乾燥する。
気−液平衡データを二元イソ酪酸(IBA)およびメタクリル酸(MAA)系について、当業者に周知の方法、例えば、Vapor−Liquid Equilibrium Data Collection,J.Gmehlingら、DECHEMA Chemistry Data Series、第I巻、40部、DECHEMA、Frankfurt,第1巻 1977に記載されているものを用いて実験的に入手した。これらのデータから、全還流での理論蒸留段の最小数を、MMAフィード中の2モル%IBA、5モル%MAAを含有するオーバーヘッドIBA流れ、および0.01モル%未満のIBAを含有するボトムMAA流れについてFenske式から計算した。理論段数の最小数は47であった。
気−液平衡データを、3成分IBA、MAAおよびジメチルスルホキシド(DMSO)系(DMSO対MAA比は2:1であった)について実験的に得た。これらのデータから、合計還流での理論的蒸留段の最低数を、IBA/MAAデータをDMSO不含基準で計算した以外は比較例3と同じ方法を用いて計算した。理論段数の最小数は27であった。
