ABSTRACT:
A catalyst for implementing a process for manufacturing amines from alcoh is composed of an active element in the transition metals family uniformly combined with a refractory porous structure with a specific surface of between 10 and 300 m.sup.2 /g and with a pore diameter less than 5000 A. A stabilizer in the form of a sodium-based compound with a sodium content of 0.15 to 20% by weight relative to the weight of the catalyst, and a promoter in the form of a rhodium-based compound with a maximum rhodium content of 0.1% by weight relative to the weight of the catalyst, may be associated with the active metal. The catalyst and the process are applicable to the ethanolamine-ammonia reaction with a view to producing ethylenediamine, piperazine, and useful byproducts.
