Abstract
Методом снятия вольт-амперных кривых исследованы анодные процессы в растворах уксусной кислоты в области высоких потенциалов без добавки и с добавкой роданида калия на платиновом электроде. Установлена роль добавки роданида калия в растворах уксусной кислоты как промотора в электрохимическом синтезе пероксиуксусной кислоты. Исследована кинетика анодного процесса в растворах уксусной кислоты в диапазоне концентраций 1...9 моль·дм⁻³. Показано, что увеличение концентрации уксусной кислоты до 6 моль∙дм⁻³ способствует достижению потенциалов электрохимического синтеза пероксиуксусной кислоты.
Anodic processes in the solutions of acetic acid without additives and with additives of potassium thiocyanate have been investigated by the voltammetry method at high potential on a platinum electrode. The role of potassium thiocyanate additive in acetic acid solution as a promoter in the electrochemical synthesis of peroxyacetic acid has been shown. Kinetics of the anode process has been investigated in the acetic acid solutions in the concentration range of 1...9 mol∙dm⁻³. It has been shown that increasing the acetic acid concentration up to 6 mol∙dm⁻³ promotes achieving the electrochemical potential of peroxyacetic acid synthesis.
