Abstract
Process comprises reacting H2S with SO2 at 100 to 180 degrees C in an organic solvent contg. an alkali metal salt of a weak acid in the presence of ammonia. Pref. the discharged gas produced in the process is cooled to 60 to 90 degrees C, the obtained aq. phase contg. ammonium sulphite separated from the gaseous phase contg. H2S and ammonia, the aqs. phsae recirculated to the reaction zone and at the same time the gaseous phase is further cooled and washed at 20 to 50 degrees C, heating and the aws. phase contng. ammonium sulphide obtained in this way heated and recirculated to the reaction zone.
