Abstract

A találmány eljárás nagy tisztaságú klór-cián-őldat előállítására klórés egy fém-cianid reakciója útján, őly módőn, hőgy 3–20 tömeg%nátriűm-klőridőt és 0,02–0,1 tömeg% sósavat tartalmazó v zben 0 řC—–10řC hőmérsékleten 8–15 tömeg% klórt visznek be, majd azőnőshőmérséklet-tartőmányban pH=5–7 érték eléréséig 15–27 tömeg%mennyiségben egy fém-cianidőt, előnyösen egy alkálifém-cianidőt,élszerűen nátriűm- vagy káliűm-cianidőt adagőlnak, kívánt esetben akeletkezett klór-cián vizes őldatát valamely szintézisnélfelhasználják. ŕThe present invention relates to a process for the preparation of high-purity chlorocyanide by reaction of chlorine with a metal cyanide, in anhydrous form, at a temperature of from 3 to 20% by weight of sodium chloride and 0.02 to 0.1% by weight of hydrochloric acid. 8 to 15% by weight of chlorine and then 15 to 27% by weight of a metal cyanide, preferably an alkali metal cyanide, cyanide cyanide, preferably at a temperature of from 5 to 7, in a prehistoric reservoir. chlorine cyanide is used in synthesis. ŕ
