Description
この方法は、少なくとも40質量%の多環オリゴマー含有率のメチレンジアニリンの水素化方法であって、以下のものを含む:
環水素化に有利な条件の下で、アルミン酸リチウム担体に担持されたロジウム/ルテニウム含有触媒系の存在下で水素とこの原料を接触させること。
・多量のオリゴマーやホルムアミド副生物によって高汚染された低価格メチレンジアニリン原料を水素化できること
・長期にわたり低価格原料の水素化に使用された触媒を再利用できること
・高い耐損耗性によって、触媒の損失および製品の汚染を最小限にできること、そして
・高い反応速度によって、高生産量を達成できること
MDA−60原料を、長さ25mで膜厚0.17μmのHP5カラムを用い、GCの面積百分率法により解析した。
水素化反応を0.5μmの触媒/生成物分離用内部フィルターを備えた標準的な1LのParr製撹拌反応器内で実施した。
アルミン酸リチウム担体上の4質量%のロジウム(3.4g)およびアルミン酸リチウム上の5質量%のルテニウム(0.45g)の物理的混合物から成る触媒系を、200gのテトラヒドロフランとともに反応器に充填した。15%の水酸化リチウムの一水和物溶液0.7gを添加し、そして触媒金属は190℃、4時間、5.85MPaゲージ水素圧(850psig)下で、1000rpmで攪拌することにより還元された。テトラヒドロフランを濾出し、そして約65%の2環MDAを含むMDA−60原料400gのTHF溶液を反応器に取り込んだ。MDAは水素の取り込みがなくなるまで、185℃、5.51MPaゲージ水素圧(800psig)、1500rpmで攪拌して水素化した。
例1に対する比較実験を、アルミナ上のロジウムおよびルテニウム触媒を用いて実施した。この触媒は市販の触媒であり、ルテニウム量は等量であるがロジウム含有率が若干高く、粗メチレンジアニリン、すなわち、MDA−85の水素化に適している。実験は、触媒が4%のアルミナ上のロジウム(4.5g)および5%のアルミナ上のルテニウム(0.45g)の混合物からなること以外は、以下のように同じ手順および同じ反応条件を用い実施された。例1および比較例2を比較した結果を表1および表2に示す。
比較例2の手順に従って、抽出したMDA原料を用いて比較実験を行った。アルミン酸リチウムに担持された触媒およびアルミナに担持された触媒を使用した。表3に結果を示す。
この例は2ステップ反応を示しており、すなわち、はじめにMDA−60原料をルテニウム/アルミン酸リチウム触媒により前処理し、そして、前処理された原料をロジウム/アルミン酸リチウムおよびルテニウム/アルミン酸リチウムの物理的混合物からなる例1の触媒系の存在下で水素化する。
