WebThe amount of thiocyanate produced is not influenced by varying the amount of potassium cyanide from 0.5 to 4.0 molar equivalents of the cystine, nor by varying the alkalinity between 0.05 and 1.0 m Na2CO3. On the other hand, heating the alkaline cystine solutions, before treating with cyanide, markedly increases their power to form thiocyanate.
