ABSTRACT:
Novel nitrogen- and sulfur-containing amphoteric compounds are prepared by reacting ammonia with a heterocyclic intermediate prepared from a nitrile, an olefin and sulfur trioxide. These compounds are useful as surfactants; those that are polymerizable form polymers which are useful as co-flocculants in combination with inorganic flocculants.
