Abstract
A process for converting the more easily synthesized and stored AMP hexahydrate into monohydrate of high purity. The resultant monohydrate (dittmarite) can then be either dried to stabilize it, or used directly in cigarette production such as paper making as filler or a filler component together with calcium carbonate.
