ABSTRACT:
A continuous reaction is carried out between gaseous SO.sub.2, I.sub.2 and liquid H.sub.2 O in a substantially vertical reaction zone. H.sub.2 O plus I.sub.2 in a substantial excess are supplied to an upper location at preselected rates. SO.sub.2 is injected into the zone at a lower location, and a desired temperature is maintained at an intermediate location where the reaction proceeds to produce sulfuric acid and hydrogen iodide. The reaction products are removed from a location near the bottom at a rate proportional to the preselected rates to cause a continuous downward flow within the reaction zone. The SO.sub.2 flow rate assures that substantially all of the SO.sub.2 either reacts or is absorbed by the downward traveling nongaseous reactants.
