Cyanate decomposition
« on: December 14, 2001, 10:56:00 PM »
Can anybody elaborate on the decomposition of cyanates to cyanides by heating? 
KCNO -heat-> KCN + CO  (supposed to take place below 800*C)
aurelius doesn't have the access to
J. Prakt. Chem. 1877 (ii) 16, 201    or
J. Prakt. Chem. 1880 (ii) 21, 77

the main concerns being
what is the minimum decomposition temperature for this rxn?
Does it need to be free of N2 or O2 to work?
Are there any particularly hazardous fumes evolved?

Also, can somebody elaborate on the decomposition of K/Na ferrocyanides to Fe, C and the respective cyanide salt?

main concerns
At what temperature does this decomposition take place?
Hazardous fumes?
