Document Type and Number:
WIPO Patent Application WO2003049850
Kind Code:
A3
Abstract:
The invention concerns a method which consists in producing powders with low hygroscopicity by vacuum drying of an aqueous solution, then by grinding, thereby obtaining a compound consisting of crystalline grains, whereof the moisture content is determined and stable. The invention is in particular applicable to organometallic complexes of glycine with a metal, wherein the glycine is bound to the metal by at least an oxygen of its carbonyl group.
