Abstract

A procedure to continuously sulfonate organic compounds with sulfur trioxide diluted in inert gas, characterized in that the organic compounds are sulfonated in a tubular reactor, in at least two stages, with the necessary sulfur trioxide, diluted in a gas inert, the organic compounds being fed in the first stage through a nozzle practically located in the center of the tube, and a part of the sulfonation gas around said nozzle, for after a residence time and/or a journey in the second stage, feed part of the sulfonation gas through another nozzle practically located in the center of the tube, while the organic compounds, with the reaction products contained therein and, eventually, with sulfur trioxide without reacting, they are driven around said nozzle.
