Synthesis and Thermal Decomposition of Di-t-Butyl Peroxydicarbonate

Article abstract of DOI:10.1246/bcsj.58.2207

Di-t-butyl peroxydicarbonate(DBPD) has been synthesized in a novel route and thermally decomposed at 40-70 deg C.The decomposition exhibits first-order kinetics and the values of ΔH^* and ΔS^* are 122 kJ mol^-1 and 46 J K^-1 mol^-1, respectively. 2-Methyl-2-propanol is obtained quantitatively as a decomposition product and the rates are a little dependant on the viscosities of solvents, normal alkanes.The mechanism that involves the initial scission of the O-O bond is discussed and the values of the rates and the activation parameters of DBPD are compared withthose of diacetyl peroxide and dibenzoyl peroxide.
