Abstract
Postupak za proizvodnju vinil acetata reagovanjem etilena, kiseonika i sirćetne kiseline koji obuhvata impergnisanje porozne podloge koja sadrži naslage katalitički delotvomih količina metalnog paladijuma i zlata, rastvorom kupriacetata, naznačen time, što je ova porozna podloga pripremljena u stupnjevima koji obuhvataju impregnisanje jedne porozne podloge vodenim rastvorom jedne količine vodorastvorljive soli paladijuma, fiksiranje tog paladijuma kao vodonerastvorljivog jedinjenja reagovanjem sa odgovarajućim alkalnim jedinjenjem, potom impregnisanje katalizatora rastvorom vodorastvorljive soli zlata, fiksiranje zlata u rastvoru koje se zateklo pri drugoj impregnaciji reagovanjem rastvorene vodorastvorljive soli u tom rastvoru odgovarajućim alkalnim jedinjenjem da bi se istaložilo vodonerastvorljivo jedinjenje zlata, i redukovanje u njihovo metalno stanje vodonerastvorljivih jedinjenja paladijuma i zlata koja se nalaze u katalizatoru. Prijava sadrži još 2 nezavisna i 12 zavisnih patentnih zahteva.A process for the production of vinyl acetate by reacting ethylene, oxygen and acetic acid, comprising the impregnation of a porous substrate containing deposits of catalytically partially metallic palladium and gold with a solution of cupriacetate, characterized in that this porous substrate is prepared in stages comprising impregnated impregnations one amount of the water-soluble palladium salt, fixing that palladium as a water-insoluble compound by reacting with an appropriate alkaline compound, then impregnating the catalyst with a solution of the water-soluble salt of gold, fixing the gold in the solution that was found at the second impregnation by reacting the dissolved water-soluble salt in the alkali a water-soluble compound of gold, and reducing to a metallic state the water-soluble compounds of palladium and gold contained in the catalyst. The application contains 2 more independent and 12 dependent patent claims.
