ABSTRACT:
With the use of an aqueous solvent containing at least water (e.g. water), and at least one organic solvent selected from esters or ketones and separable from the aqueous solvent, the processes of the invention separate (1) an adamantanediol and an adamantanepolyol having three or more hydroxyl groups per molecule, from a group of adamantanepolyols having plural hydroxyl groups per molecule, distributing the former into an organic solvent layer and the latter into an aqueous solvent layer. Further, (2) an adamantanemonool and the group of adamantanepolyols can be separated from a group of adamantanols having at least one hydroxyl group per molecule with using an aqueous solvent (e.g. aqueous solution of acetic acid) for crystallization of the adamantanemonool.
