Improved solvation routes for the Bunsen reaction in the sulphur iodine thermochemical cycle: Part III-Bunsen reaction in molecular solvents

► Bunsen reaction in Cyanex® 923 is investigated. ► The solvation effects of the Bunsen reaction are discussed. ► Presence of an SO2-HI-solvent complex is identified. ► Limitations of analytical procedures for Bunsen reaction in solvents are discussed.
