A B S T R A C T Sulph(on)ation of organic feedstock is performed with undiluted sulphur trioxide in a recycle loop reactor in which the feedstock is diluted with its recycled sulph(on)ation product, contact of the feedstock and sulphur trioxide occurs under conditions of turbulent flow and the recycle ratio is high. The turbulent flow is preferably in a novel orifice plate mixer suitable for general application in which the axial orifice of the mixer, through which a first fluid, part- icularly containing the feedstock, passers, has in its internal wall a port through which a second fluid, particularly sulphur, trioxide, passes.
