Abstract

1288835 Sulphuric acid NAUCHNO-ISSLEDOVATELSKY INSTITUT PO UDOBRENIYAM I INSEKTOFUNGITSIDAM IMENI PROF YA V SAMOILOVA 19 March 1970 13386/70 Heading C1A H 2 SO 4 is prepared by forming a gaseous mixture of SO 3 and H 2 O which is then sprayed with 78-98% H 2 SO 4 in two stages, at 90-200‹ C. and at 40-70‹ C., to form a gaseous product containing liquid H 2 SO 4 which is separated. The gaseous mixture may be formed by burning S containing raw material and treating the resulting SO 2 and H 2 O with a solid catalyst. The product acid may be in the form of a fog which is filtered, e.g. through a fibrous filter.
