Abstract
Postupak za proizvodnju vinilacetata, naznačen time, što se sastoji od (a) napajanja reaktora etilenom, sirćetnom kiselinom i gasom koji sadrži kiseonik, sjedinjavanjem etilena sirćetne kiseline i gasa koji sadrži kiseonik na povišenoj temperaturi u reaktoru, u prisustvu materijala katalizatora (i) da bi se dobila smeša proizvoda, koji sadrži vinilacetat, (ii) tečni sporedni proizvod, koji sadrži sirćetnu kiselinu i vodu, i (iii) gasoviti sporedni proizvod, koji sadrži ugljen-dioksid; (b) izdvajanja tečnog sporednog proizvoda iz smeše proizvoda; (c) tretiranja tečnog sporednog proizvoda, kako bi se snizio sadržaj vode u njemu; i (d) reciklisanje tretiranog tečnog sporednog proizvoda u reaktor, pri čemu se podrazumeva da je količina vode koja ulazi u reaktor manja od 6 mas%, poželjno manja od 4 mas%, a još poželjnije manja od 3 mas%, računato na ukupnu sirćetnu kiselinu i vodu koji ulaze u reaktor. Prijava sadrži još jedanaest zavisnih patentnih zahteva.A process for the production of vinyl acetate, comprising (a) supplying the reactor with ethylene, acetic acid and oxygen containing gas, by combining ethylene with acetic acid and oxygen containing gas at elevated temperature in the reactor, in the presence of catalyst material (i) that to produce a mixture of a product containing vinyl acetate, (ii) a liquid by-product containing acetic acid and water, and (iii) a gaseous by-product containing carbon dioxide; (b) separating the liquid by-product from the product mixture; (c) treating the liquid by-product in order to reduce the water content thereof; and (d) recycling the treated liquid by-product into the reactor, assuming that the amount of water entering the reactor is less than 6 wt%, preferably less than 4 wt%, and more preferably less than 3 wt% acid and water entering the reactor. The application contains eleven dependent patent claims.
