Abstract: A process is provided for making acyloxy benzene sulfonates by the steps of sulfonating with SO.sub.3, digesting the sulfonation adduct, and neutralizing. The sulfonation adduct can spontaneously rearrange. Unless the rearrangement is controlled as taught in the sulfonating and digesting steps, product yields of acyloxy benzene sulfonate drop to unusable levels and the color of the product is poor and the content of by-products is excessive in the product.
