Abstract

POSTUPAK I UREDJAJ ZA PROIZVODNJU HLORATA ALKALNOG METALA, ovaj pronalazak se odnosi na postupak za izradu hlorata alkalnog metala elektrolizom u ćeliji sa membranom (3) anolita koji sadrži rastvor hlorida alkalnog metala i katolita koji sadrži rastvor hidroksida alkalnog metala, pri čemu se rastvor hlorida alkalno metala prethodno prečišćava sledećim uzastopnim fazama: - elektrolizom u ćeliji tipa "hlor-natrijum hidroksid" (1) rastvora soli hlorida alkalnog metala da se s jedne strane nagradi gasoviti hlor, i s druge strane koncentrovan rastvor hidroksida alkalnog metala, - prebacivanjem proizvoda gasovitog hlora i rastvora hidroksida alkalnog metala, u kolonu za obaranje (2) da medjusobno reaguju, i - izdvajanjem tako dobijenog rastvora soli, za njegovu primenu kao anolita u ćeliji sa membranom (3). Ovaj pronalazak se isto tako odnosi na uredjaj za izvodjenje ovog postupka i uredjaj za prečišćavanje slanog rastvora hlorida alkalnog metala.
