Abstract
U postupku za uklanjanje etil acetata iz procesne materije koja sadrži vinil acetat, acetilnu kiselinu, vodu i nečisti etil acetat, kroz korake: (a) uvodjenje procesne materije u destilacioni stub, (b) destilovanje procesne materije da bi se dobili vinil acetat-frakcija na višem kraju destilacionog stuba i acetilna kiselina-frakcija na nižem kraju destilacionog stuba, i (c) izdvajanje bočnog jedinjenja koje sadrži etil acetat iz srednjeg dela destilacionog stuba, ustanovljeno je da je u slučaju izdvajanja bočnog jedinjenja u gasovitom stanju, koncentracija etil acetata postignuta u destilacionom stubu viša nego koncentracija postignuta izdvajanjem bočnog jedinjenja u tečnom stanju, i da je ta masena koncenetracija veća od 10 %.
