Abstract
Inventia se refera la un procedeu pentru obtinerea unui catalizator de argint utilizat la producerea oxidului de etilena. Procedeul consta în impregnarea suportului de alumina mai întîi cu o solutie a unui metal alcali, de preferinta cesiu, dupa care acesta se usuca, cel putin partial, într-un curent de azot, la o temperatura de 100...200 degree C, apoi se pune în contact cu o faza lichida, continînd o solutie apoasa a unui compus de argint, cu un acid carboxilic si un agent alcalin solubilizant reducator, format dintr-o amina organica, cum ar fi, 1,2-diaminoetan si, în final se trateaza termic în prezenta unui agent reducator, la o temperatura de 100...375 degree C.
