Abstract
în cadrul procedeului, conform inventiei, catalizatorul din argint pe suport ce urmeaza a fi tratat, este impregnat cu o solutie constând din hidroxid de cesiu, un alcoolat de cesiu al unui alcool alifatic inferior saturat sau dintr-un amestec al acestora drept compus de cesiu si dintr-un alcool alifatic saturat inferior si 0..20% în greutate apa ca solvent la o temperatura de 60..200 degree C, prin care pe catalizatorul din argint pe suport ce urmeaza a fi tratat se aplica la 1000 mg cesiu pe kg catalizator. Acesti catalizatori pe suport din argint sunt utilizati în special la prepararea oxidului de etilena prin reactionarea etilenei cu oxigen sau aer.
