Metal hydrogensulfates were used as an efficient reagent system for the preparation of organic compounds and so the acceleration of some organic reactions. In this paper we wish to report a simple, cheap and clean method for preparation and separation of some these products.

Metal hydrogensulfates, heterogeneous reaction conditions, separation processes,
