Abstract

Abstract: An experimental technique has been designed which allows time resolved in situ FT-IRspectroscopic measurement of the reduction of the SOCl₂.SO₂Cl₂, SO·SOCl₂, (SO)_x, Cl₃Al(←OSCl₂)are observed as intermediates in the electrochemical reduction of SOCl₂ on the Pt electrode.The results show that the intermediates are unstable and the further electrochemical reduction of SOCl²⁺2e→SO²⁺2Cl- is the rate determination step of SOCl₂.According to the experimental result, the possibility of the electrochemical reduction steps of S₂OCl₂ is discussed.

Key words: Thionyl chloride, Electrochemical reduction, Intermediate species, In situ FTIR spectroscopy
