This work deals with the investigation of the Bunsen reaction. An experimental campaign was conducted by means of a stirred reactor. Runs were carried out in a semibatch mode by feeding gaseous sulphur dioxide in a iodine/hydriodic acid/water solution. The purification of the produced hydriodic phase was also investigated. It was shown that both the amount of absorbed SO2 and its conversion lowered as the temperature increased. Purification of the hydriodic phase was only possible at high temperature and high iodine contents.
