Abstract

Procedimiento para la precipitación de partículas sólidas finamente divididas. Comprende a) Disolver un compuesto C en un fluido A para obtener una solución A; b) Termostatizar dicha solución A a una temperatura comprendida entre -50°C y 200°C; c) Añadir a dicha solución A un fluido B hasta alcanzar una presión P, y se caracteriza por el hecho de que dicho fluido B a una presión P es miscible con dicha solución A y actúa como co- solvente para formar una solución AB; y d) Reducir la presión de dicha solución AB para que tenga lugar la precipitación de dicho compuesto C. El procedimiento permite obtener partículas de tamaño medio inferior a 20 mm, generalmente inferior a 10 mm, con una distribución estrecha de tamaño comprendida entre 1 y 100 mm, generalmente entre 1 y 20 mm, a partir de una solución, y no una mezcla, que contiene el compuesto a precipitar.
