Kinetics and mechanism of decomposition of dibenzoylfuroxane

The kinetics of decomposition of dibenzoyl furoxane (DBFO) in a melt and in dilute solutions in biphenyl and nitrobenzene at a temperature of 116–141 °C was studied by the calorimetric method. As a result of the decomposition of DBFO, a substance is formed, which by its nature is also furoxane, but differs in a more complex structure and a higher decomposition temperature. The high rate and unusual composition of the decomposition products of DBFO are explained within the framework of the biradical mechanism of decomposition of furoxanes.
