Abstract
Inventia se refera la un procedeu de recuperare, prin rectificare la presiune atmosferica pe o coloana cu functionare continua, a solventilor rezultati de la sinteza polifenilenoxidului. Amestecul azeotrop benzen-izopropanol colectat, ca fractie laterala, la coloana continua de rectificare precum si distilatul (continând morfolina, izopropanol, benzen) rezultat la distilarea simpla a produsului de blaz al coloanei este recirculat la faza de sinteza a polifenilenoxidului. Faza organica a produsului separat la vârful coloanei de rectificare este recirculata la alimentarea coloanei.
