| description | Method for Preparing a target substance in particulate form, comprising introducing into a particle formation vessel, through separate first and second fluid inlet means respectively, (a) a "target solution/suspension" of the substance in a fluid vehicle and (b) a compressed fluid anti-solvent, and allowing the anti-solvent to extract the vehicle so as to form particles of the substance, wherein the anti-solvent fluid has a sonic, near-sonic or supersonic velocity as it enters the vessel, and wherein the anti-solvent and the target solution/suspension enter the vessel at different locations and meet downstream (in the direction of anti-solvent flow) of the second fluid inlet means. Also provided is apparatus for use in such a method.
Se describe un metodo para preparar una sustancia objetivo en forma de particulas, que comprende introducir a un recipiente de formacion de particulas, a traves de primeros y segundos medios de entrada de fluido separados, respectivamente, (a) una "solucion/suspension objetivo" de la sustancia en un vehiculo fluido y (b) un antisolvente de fluido comprimido y permitir que el antisolvente extraiga el vehiculo para formar particulas de la sustancia, en donde el fluido antisolvente tiene una velocidad sonica, casi sonica o supersonica a medida que entra al recipiente y en donde el antisolvente y la solucion/suspension objetivo entran al recipiente en diferentes sitios y se encuentran corriente abajo (en la direccion del flujo del antisolvente) de los segundos medios de entrada del fluido. Tambien se proporciona un aparato para uso en tal metodo. |
