ABSTRACT:
A continuous process is disclosed which comprises introducing a sulfonatable or sulfatable organic liquid onto a rotating reaction surface as a thin film, rotating the reaction surface at a velocity such that the thin film is continuously moved toward the periphery of the reaction surface, dividing the reaction surface into a plurality of areas, depositing within each area a controlled quantity of gaseous sulfur trioxide over the liquid film, maintaining the pressure during the reaction at subatmospheric levels, controlling the temperature of the reaction surface, moving the reaction product by centrifugal action to the periphery of the reaction surface and continuously collecting the reaction product.
An apparatus for carrying out such a process is also disclosed.
