PROCESS FOR PRODUCING FINE PARTICLES WITH REGULATED PARTICLE DIAMETER

WIPO Patent Application WO/2012/014530

A1

A process for producing fine particles having a regulated particle diameter is provided in which use is made of a device in which fluids are treated between at least two treatment surfaces which have been approachably and separably disposed face to face, at least one treatment surface rotating relatively to the other. A device in which fluids are treated in a thin fluid film formed between at least two treatment surfaces (1 and 2) which have been approachably and separably disposed face to face, at least one treatment surface rotating relatively to the other, is used to mix at least two fluids to be treated, i.e., a raw-material solution comprising a solvent and, dissolved therein, a substance to be precipitated and a precipitation solvent for precipitating the substance to be precipitated, to precipitate fine particles of the substance. The viscosities of the fluids to be treated which are introduced into the space between the treatment surfaces (1 and 2) are regulated to thereby obtain the fine particles having a regulated particle diameter.
