Abstract

Катализаторите се използват при окисляване на етилен в парова фаза с молекулен кислород до етиленов окис. По метода се импрегнира носител с въглеводороден разтвор на сребърна сол на неокиселини, представляващи триалкилни оцетни киселини. Носителят е избран от групата на алуминиев окис, силициев двуокис, алумосилициев окис или техни смеси. Катализаторите могат в даден случай да бъдат промотирани с цезий, калий или рубидий. 16 претенции
