Abstract:
     A carbonate or bicarbonate is used to obtain phenanthridine and then a hydrochloric acid, or lactic acid, or oxali acid process is used to obtain a phytic acid from the phenanthridine. The hydrochlori acid or lactic acid process features that the phytic acid is obtained in two steps: obtaining a clear liquid with a strongly acidic cation exchange resin and then obtaining the phytic acid by fractional distillation at a temp. less than 100 deg.C after ordinary-pressure distillation. The oxalic acid process features that the phytic acid is obtained through such processes as cooling, filter, fractional distillation of filtered liquid at a temp. less than 100 deg.C, concentration, cooling the concentrated liquid, second filter and second fractional distillation of filtered liquid at a temp. less than 100 deg.C.
