Abstract
Pronalazak se odnosi na suvi postupak proizvodnje kalijum-sulfata i amonijum-hlorida konverzijom iz kalijum-hlorida i amonijum-sulfata. Prema ovom postupku sitno samlevene sirovine KCl i (NH4)2SO4 mešaju se u molskom odnosu Cl : N 1-1, 20 i zagrevaju na atomosferskom pritisku u intervalu temperature 150-150 stepeni. Nastala gasna faza u toku reakcije, odvodi se iz reakcionog prostora na hladjenje i kristalizaciju, pri čemu se izdvaja amonijum-hlorid velike čistoće, a kao čisti ostatak u rektoru dobija praktično bezhloridnu kalijum-sulfat.
