Combustion cyanogen

Particularly important compounds have been studied by flame combustion calorimetry. Methane [92-94], ethanol [95], diethyl ether [96], carbon monoxide [92,93,97], hydrochloric acid [98], and water [93,97,99] are representative examples. With a few exceptions (HC1, H2O, D2O [100], SO2 [101], cyanogen [102,103], and some lower chloroalkanes [104,105]), measurements by flame combustion calorimetry have been limited to substances of general formula CaHbOc. 

J. Thomsen11 found the heat of formation of gaseous nitrous oxide from its elements to be —18-32 Cals. and M. Berthelot, —20-6 Cals, for the gas, —18-0 Cals, for the liquid and —14-4 for the gas in aq. soln. J. Thomsen gave for (NO,N2), 3-255 Cals. M. Berthelot and P. Vieille calculated the temp, of combustion of a mixture of nitrous oxide and cyanogen to be 3596°-4149°. J. C. Thomlinson calculated what he called the thermochemical eq. of the nitrogen contained in nitrous oxide—vide infra.
