Description
Najdluzszy czas trwania patentu do 15 pazdziernika 1943 r.W patencie glównym Ner 9526 opisano sposób otrzymywania cyjanków alkalicz¬ nych, polegajacy na przepuszczaniu przez tlenki lub wodorotlenki lub sole alkaliczne mieszaniny tlenku wegla i gazu amonja- kalnego w temperaturze najkorzystniej 400 — 800°.Ponizej przytacza sie przyklad otrzy¬ mywania cyjanków alkalicznych, w któ¬ rym zamiast tlenków lub wodorotlenków alkalicznych stosuje sie sole alkaliczne.Przyklad- Mieszanine 50 cz. wag. gazu amonjakalnego i 50 cz. wag. tlenku wegla przepuszcza sie, mieszajac, w temperatu¬ rze okolo 600° przez stop zawierajacy 25 cz. wag. cyjanku sodowego i 75 cz. wag. weglanu sodowego, poczem cyjanek od¬ dziela. PLThe longest term of the patent until October 15, 1943 The main patent Ner 9526 describes a method of obtaining alkaline cyanides by passing through oxides or hydroxides or alkali salts a mixture of carbon monoxide and ammoniacal gas at a temperature of preferably 400-800 ° C. an example of the preparation of alkaline cyanides in which alkali salts are used instead of alkali oxides or hydroxides. wt. ammoniacal gas and 50 parts wt. The carbon monoxide is passed with stirring at a temperature of about 600 ° through an alloy containing 25 parts of wt. sodium cyanide and 75 parts wt. sodium carbonate, then the cyanide was separated.
