Descomposicion termica del diperoxido de pinacolona (3,6-diterbutil-3,6-dimetil-1,2,4,5-tetraoxaciclohexano) en solución de 2-metoxietanol

Abstract

Recebido em 5/1/01; aceito em 14/11/01 THERMAL DECOMPOSITION OF PINACOLONE DIPEROXIDE (3,6-ditertbutyl-3,6-dimethyl-1,2,4,5-tetraoxacyclohexane) IN 2-METHOXYETHANOL SOLUTION. The thermal decomposition reaction of pinacolone diperoxide (DPP; 0.02 mol kg -1 ) in 2-methoxyethanol solution studied in the temperature range of 110.0-150.0 °C, follows a first-order kinetic law up to at least 50% DPP conversion. The organic products observed were pinacolone, methane and tert-butane. A stepwise mechanism of decompositi…
