A process for producing an ethylenamine, which comprises reacting ammonia and/or an ethylenamine with an ethanolamine in the presence of hydrogen to obtain an ethylenamine 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 M elements 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.

Process for producing an ethylenamine

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

Process for producing a polyalkylene polyamine

A mixed oxide catalyst comprising niobium oxide and a member selected from the group consisting of titania, alumina, silica, zirconia and oxides of elements in Groups IIA, VA, VIA, IB, IIB, IIIB, VB, VIB, VIIB and VIII of the Periodic Table. A process for producing an alkylenamine, which comprise reacting ammonia and/or an alkylenamine with an alkanolamine in the presence of such a mixed oxide.
