ABSTRACT:
Free flowing, substantially pure, non-hygroscopic, crystalline .beta.-D-gulopyranose is disclosed. This crystalline form of D-gulose is characterized by a sharp melting point of 130.degree.-132.degree. C., a specific optical rotation of -40.degree. and characteristic mutarotation. A method for preparation of crystalline .beta.-D-gulopyranose from D-gulose syrup is also disclosed. This method involves dilution of the D-gulose syrup, followed by initiation of crystallization, and isolation of .beta.-D-gulopyranose crystals. Crystalline .beta.-D-gulopyranose may be used as an excipient, a chelating agent, a pharmaceutical intermediate, a cleaning agent for glass and metals, a food additive, and as an additive for detergents.
