Decomposition of organic hydroperoxides on cation exchangers XV. The kinetics of the decomposition process of p-isopropylcumene hydroperoxide on a catalyst of montmorillonite type

The decomposition of p-isopropylcumene hydroperoxide on a catalyst of montmorillonite type containing Sn²⁺ ions, Sn²⁺-K10 showed first order kinetics in the range of 45-55°C. The activation energy, the enthalpy of activation, the entropy as well as the Gibbs free energy of activation were calculated for the investigated temperature region. Acetone and p-isopropylphenol were produced by this chemical decomposition; both compounds are important intermediates in the chemical industry.
