This high flame temperature is partially due to the absence of hydrogen in the fuel (dicyanoacetylene is not a hydrocarbon) thus there is no water among the combustion products . </P> <P> Cyanogen, with the formula (C N), produces the second - hottest - known natural flame with a temperature of over 4,525 ° C (8,177 ° F) when it burns in oxygen . </P>
