Abstract

POSTUPAK ZA DOBIJANJE SREBROVIH SOLI, koje se koriste za dobijanje podloge od srebrovih katalizatora pogodnih za oksidaciju etilena do etilen oksida, tako što se vrši impregnisanje podloge ugljovodoničnim rastvorom srebrove soli, naznačen t ime, što se so srebra dobija reakcijom jedinjenja srebra kao što je srebro oksid ili srebro karbonat sa neokiselinom koja ima više od 7 atoma ugljenika, kao što je neodekanska ili neotridekanska kiselina u prisustvu agensa za rastvaranje, alkohola, kao što je etanol, što se srebro odvaja uvodjenjem agensa za taloženje, alkohola, kao što je etanol, i što se odvojena so srebra pere radi uklanjanja kiseline. Prijava sadrži još 1 nezavisan zahtev.
