Description
本発明は、遷移金属−不均一系触媒の存在下でのモノエタノールアミン(MEOA)とアンモニアとの反応によるエチレンアミンの製造方法に関する。
1.成形体の内側多孔率を決定(例えば、室温及び1barの全体圧での、[ml/g Kat(触媒)]での水吸収の測定を介して)、
2.液体中への浸漬の際の成形体の排除量(例えば、ヘリウムピクノメーターを用いたガス排除量)を決定、及び
3.両方の体積の合計を形成。
この表面積は以下の方法によって理論的に計算されることもでき、その際この成形体の包絡面(Umhuellend)を定義し、その曲線半径は最大で5μmであり(この細孔中への包絡線の「侵入」による内側細孔表面積を連行しないように)、及び、この包絡面はこの成形体に可能な限り密接に接する(担体との断面積(Schnittflaeche)無し)。具体的には、これは、成形体周囲に配置され、次いで中から真空を適用した極めて薄いシートに相応するものであり、この結果前記シートは可能な限り密に成形体周囲に配置される。
Al2O3として計算して、アルミニウムの酸素含有化合物、20〜90質量%、有利には40〜85質量%、特に有利には60〜80質量%、
CuOとして計算して、銅の酸素含有化合物、1〜30質量%、有利には2〜25質量%、特に有利には3〜20質量%、
NiOとして計算して、ニッケルの酸素含有化合物、1〜40質量%、有利には3〜30質量%、特に有利には5〜20質量%、その際特に有利にはニッケルと銅のモル比は1より大きく、有利には1.2より大きく、特に有利には1.8〜8.5である、及び、
CoOとして計算して、コバルトの酸素含有化合物、1〜40質量%、有利には3〜30質量%、特に有利には5〜20質量%。
その際Apは、この触媒粒子の外側表面積(mms 2)、そして、Vpは、この触媒粒子の体積(mmp 3)である
(L=触媒成形体の比による寸法(Spezifische Dimension))。
以下の触媒を、エチレンアミンへの、MEOAとアンモニアとの反応のために使用した:
全ての触媒は、Cu/Co/Ni/ガンマAl2O3−触媒であり、これらは例えばDE-A-19 53 263 (BASF AG)中に開示され、かつ、含浸により製造された。
ガンマAl2O3に対して、CoO10質量%、NiO10質量%、及び、CuO4質量%。
