Beschreibung
Zusammenfassung:	The present invention provides a new and improved method of forming Ferric maltol by reacting a Maltol in an organic alkaline solution/slurry with a non-carboxylate iron salt in an organic solvent. The present invention also provides an improved process for the preparation of polymorphic form alpha of ferric maltol. The present invention further provides novel polymorphic forms RK1, RK2, RK3, RK4, RK5, RK6 and RK7 of Ferric maltol with a characteristic XRPD Patterns respectively and process for their preparation thereof.
