Abstract

The determination of chemical kinetics constant of triphenyltin(IV) p-hydroxybenzoate by the use of cyclic voltammetry has been performed, The compound used was previously synthesized and well characterized and has been applied as anticorrosion inhibitor. The determination of kinetic constants of this compound will be useful to assess future reactivity through the value of forward chemical reaction rate constant (k ). In this study, carbocation intermediate was produced by oxidizing the compound, which will then react chemically with nucleophilic solvent. The measurement of standard solution triphenyltin(IV) p- hydroxybenzoate was at concentration of 0.8 mM in the water system: DMSO (3: 1) was monitored by cyclic voltammetry with the condition of a potential windows of 700 mV to 1400 mV; potential scan rate variation (ν) at intervals of 100 mV: 100-1000 mV/sec; the working electrode of gold (Au), reference electrode platinum (Pt) and the reference electrode of silver (Ag); and supporting electrolyte solution of sodium chloride 0,02 M. To obtain the value of the following chemical reaction rate constant of triphenyltin(IV) p-hydroxybenzoate on the cyclic voltammogram, we used digital simulation method using Polar 5.8.3 software. The results showed that the rate of subsequent chemical reactions constant compound triphenyltin(IV) p-hydroxybenzoate was a function of the potential scan rate, k f f = 3.45 ν + 0.45 (r = 0.994) with a slope value of (k f /ν) = 3.45/V. The type of chemical reaction mechanisms occurred in around the working electrode surface following the E q C i . .
