A process of synthesizing HBIW using a mineral acid, such as perchloric acid, as the acid catalyst is disclosed. According to the process, glyoxal, adjusted to a pH from 4 to 7, and benzylamine are reacted in the presence of the mineral acid for sufficient time to form HBIW. The resulting HBIW is then isolated according to conventional separation techniques.
