SYNTHESIS OF SMALL PARTICLES

The invention provides a method for forming fine particles of a substance, the method including contacting a non-gaseous fluid containing the substance with a dense gas to expand the fluid, the dense gas including (a) an anti-solvent and (b) a modifying agent which modifies the polarity of the anti-...

Beschreibung
Zusammenfassung:	The invention provides a method for forming fine particles of a substance, the method including contacting a non-gaseous fluid containing the substance with a dense gas to expand the fluid, the dense gas including (a) an anti-solvent and (b) a modifying agent which modifies the polarity of the anti-solvent, and particles formed by the method. L'invention concerne un procédé de formation de fines particules d'une substance, le procédé consistant à mettre un fluide non gazeux contenant la substance en contact avec un gaz dense afin de dilater le fluide, le gaz dense contenant (a) un anti-solvant et (b) un agent modifiant lequel modifie la polarité de l'anti-solvant, ainsi que les particules formées par le procédé.
