Abstract:
A process for producing pulverous, i.e., powdered, preparations from sparingly soluble solid materials is disclosed. The process utilizes dimethyl ether under conditions of elevated temperature and pressure to dissolve the solid material. Upon release of the pressure, the solid material precipitates as a fine powder and the gaseous dimethyl ether is released or drawn off.
