Abstract

Crude aqueous solutions of inositol obtained by hydrolysis of phytates are refined by neutralizing the phytate hydrolysate with at least one alkaline substance from the group calcium oxide, hydroxide or lime-inositol complex to a pH from about 6 to about 7, removing the precipitate, further treating the phytate hydrolysate with at least one of the above alkaline substances to increase the pH to within about 8.5 to about 10, removing the precipitate, and crystallizing inositol from the filtrate. The mother liquor from this final filtration may be treated with calcium oxide or hydroxide or mixtures thereof, preferably using at least one mol. per mol. of inositol present, to precipitate a lime-inositol complex. This may be treated with an acid substance to liberate inositol and form an insoluble salt with the calcium, e.g. phosphoric acid or carbon dioxides or the lime inositol complex may be used as an alkaline reagent in the initial neutralization of the phytate hydrolysate. In the examples there are exemplified various aspects of the invention.
