Abstract

The mono-o-phosphate of aneurin-o-phosphoric acid ester is obtained by reacting aneurin-o-phosphoric acid ester with at least 1 mol. of o-phosphoric acid or by converting a mono-salt of aneurin-o-phosphoric acid ester other than the mono-o-phosphate by double decomposition or an anionic exchange into the mono-o-phosphate. Examples utilize aneurino-phosphoric acid ester chloride-hydrochloride as starting material.
