in neat (no solvent) byproducts: SO3; prepn. by flow method; Bi2O3 placed to a heated tubular reactor with inert gas passing through it; after achieving a given temp. inert gas flow replaced by flow of Cl2 and SO2 (1:1); linear gas speed was 0.02-0.05 m/s; temp. was 550-750°C; volatiles trapped in cooled traps; monitored by X-ray diffraction and chem. analysis;
