Reaction Steps

200 g of H3PO4 (85%) in 200 cc of H2O were reacted with 77 g of piperazine (97%) in 300 cc of H2O at a maximum temperature of 65° C. and at a pH of about 5. The precipitate, consisting of the acid orthophosphate of piperazine, was maintained at a temperature from 0° to 5° C. for about 20 hours, then it was filtered and dried.
