The electrosorption behavior of tert-butyl alcohol at the mercury|aqueous NaClO4– tetramethylthiourea was determined by a double layer differential capacity measurement. Adsorption of tert-butyl alcohol was analyzed using the constants obtained from the modified Flory–Huggins and virial isotherm. An increase in the relative surface excess for tert- butyl alcohol with increasing NaClO4 concentration in the range from 0.1 to 1.0 M was confirmed. The observed effect may be the result of the weakest repulsive interaction between adsorbed tert-butyl alcohol molecules in 1.0 M NaClO4 with 0.05 M tetramethylthiourea.

Kinetics Of

The kinetics of oxidation of [Co(en)2SCH2COO]+ with S2O82- was studied in water-methanol and water-tert-butyl alcohol mixtures. Changes in the reaction activation parameters ∆H≠ and ∆S≠ with varying concentration of the co-solvent depend on the kind of the latter, which points to a significant role of salvation effects. The solvation effect on the reaction is discussed based on a comparison of the transfer functions ∆Ht0, ∆St0 and ∆Gt0 for the initial and transition states with the changes in the activation parameters accompanying changes in the CO-solvent concentration. The transfer enthalpies of the reactant were obtained from calorimetric measurements.
