Abstract:
A process for producing ethylenamines,which comprises reacting ammonia and/or an ethylenamine with an ethanolamine in the presence of hydrogen to obtain ethylenamines having an increased number of ethylene chains over the ammonia and/or the ethyelenamine used as the starting material, wherein a catalyst comprising Ni and at least one element M, wherein M is at least one rare earth element selected from the group consisting of scandium, yttrium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium, is used for the reaction.

Abstract:
A process for producing alkylenamines, which comprises reacting ammonia and/or an alkylenamine with an alkanolamine to obtain an alkylenamine having an increased number of alkylene units over the ammonia and/or the alkylenamine used as starting material, wherein a catalyst having a niobium-containing substance supported on a carrier is used for the reaction.
Abstract:
