ABSTRACT:
An organic reactant is sulfonated by injecting it into a stream of gas comprising sulfur trioxide, at a venturi, and the resulting reaction mixture is quenched with a stream of cooled, recycled reaction product immediately downstream of the venturi in a conduit in which particles of reaction mixture are agglomerated into a film of the recycle stream and in which additional sulfonation reaction occurs.
