Process for producing ethyleneamines

In the manufacturing method of the monoethanolamine (MEOA) under existence of a transition metal * heterogeneous catalyst, and ethylene amine by the reaction of ammonia, The catalyst active material of the above-mentioned catalyst contains aluminum, copper, nickel, and the oxygen content compound of cobalt, before processing from hydrogen, and it is this catalyst fabrication object, In the case of a globular form or the Strand form, it has each time diameter L=1/a'<0.70mm which corresponds diameter <3mm each time in the case of the geometry of everything [case / of a tablet form] but height <3mm and all, and a' is an outer surface product (mm) per volume unit in that case.s2/mmp3It is, is here and is a'=A.p/VpCome out, and it is and is in that case A.pは, the outer surface product of this catalyst particle (mm)s2And VpVolume of は and this catalyst particle (mm)p3it is -- the manufacturing method of the monoethanolamine (MEOA) under existence of the transition metal * heterogeneous catalyst characterized by things, and ethylene amine by the reaction of ammonia.
