Abstract

1. Process for the manufacture of chlorosulfonic acid from hydrogen chloride and sulfur trioxide dissolved in chlorosulfonic acid, characterized by mixing the sulfur trioxide dissolved in chlorosulfonic acid and hydrogen chloride gas in a Venturi nozzle, allowing them to react and keeping the temperature at the end of the Venturi tube in the range of from 70 to 100 degrees C.
