Can anybody elaborate on the decomposition of cyanates to cyanides by heating? <br>KCNO -heat-> KCN + CO (supposed to take place below 800*C)<br>aurelius doesn't have the access to <br>J. Prakt. Chem. 1877 (ii) 16, 201 or<br>J. Prakt. Chem. 1880 (ii) 21, 77<br><br>the main concerns being <br>what is the minimum decomposition temperature for this rxn?<br>Does it need to be free of N2 or O2 to work?<br>Are there any particularly hazardous fumes evolved?<br><br>Also, can somebody elaborate on the decomposition of K/Na ferrocyanides to Fe, C and the respective cyanide salt?<br><br>main concerns<br>At what temperature does this decomposition take place?<br>Hazardous fumes?<br><br><br>
