Di-<I>t</I>-butyl peroxydicarbonate(DBPD) has been synthesized in a novel route and thermally decomposed at 40–70 °C. The decomposition exhibits first-order kinetics and the values of Δ<I>H</I><SUP>\neweq</SUP> and Δ<I>S</I><SUP>\neweq</SUP> are 122 kJ mol<SUP>−1</SUP> and 46 J K<SUP>−1</SUP> mol<SUP>−1</SUP>, 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 with those of diacetyl peroxide and dibenzoyl peroxide.
