KINETICS OF DECANE SULFOPERACID THERMAL-DECOMPOSITION IN THE PRESENCEOF ALCOHOLS AND SATURATED-HYDROCARBONS

The kinetics of thermal decomposition of decane sulfoperacid in a carb on tetrachloride medium at 313-333 K in air in the presence of ethanol , n-octanol, cyclohexanol, isopropanol, cyclohexane, and isooctane (rH ) was studied. The kinetics of peracid consumption was described by eq uation dC/dt = k(1)C + k(2)C[rH]. The rate constants k(2) and the part ial rate constants k(2)(CH) were determined. For isooctane and alcohol s, the relationship between the partial rate constant k(2)(CH) and the rH structure was described by the Okamoto-Brown equation. The logarit hm of the partial rate constant log(k(2)(CH)) dropped linearly as the alpha-CH bond strength in alcohols increased. The linear relationship between the activation energy E-2 and the logarithm of the preexponent ial factor A(2)(CH) was observed.
