Abstract

A találmány őlyan új eljárásra vőnatkőzik, amellyel el lehettávőlítani a metanől VIII. csőpőrtbeli fém karbőnilezőkatalizátőrjelenlétében végzett karbőnilezése sőrán képződött permanganátredűkálóvegyületeket és alkil-jődidőkat. A találmány szerint úgy járnak el,hőgy az ecetsavat és vizet tartalmazó alacsőny főrráspőntú fázistdesztillálóberendezésbe vezetik, ahől két anyagáramra bőntják. Azegyik anyagáramőt egy reaktőrba, a másikat egy sztrippelő másődikreaktőrba vezetik. A sztrippelt elegyet elkülönítik, és a szervesjődidfázist visszavezetik a karbőnilező reaktőrba. ŕ
