Mulitube falling-film reactor for the continuous sulfonation and sulfation of fluid-state organic substances by reaction with gaseous sulphuric anhydride (SO.sub.3), has each tubular element non-permanently fixed to the plates and has a nozzle (10) fitted in a sleeve (20) integral with a reaction tube (23). The nozzle (10) can slide within the sleeve (20) and may be placed at different heights with respect to the latter, forming with the end-piece (14) a cylindrical crown opening (18) of fixed width and variable height. Such arrangement permits to control the delivery of the fluid to be sulfonated. The opposite end of each tube (23) fits into a double-plate seal system.
