Abstract

Un proceso para preparar partículas de una sustancia que comprende poner en contacto una primera formulaciónque incluye una primera sustancia en disolución en un disolvente portador orgánico con una primera corriente de undisolvente de hidrofluorocarbono C1-4 y una segunda corriente de un disolvente de hidrofluorocarbono C1-4 que es elmismo que el de la primera corriente, siendo el disolvente portador miscible con el disolvente de hidrofluorocarbonoC1-4, siendo la primea substancia insoluble o ligeramente soluble en el disolvente de hidrofluorocarbono C1-4,causando de este modo la precipitación de partículas de la primera sustancia, en donde la primera y segundacorriente del disolvente están en un estado no supercrítico, y someter la mezcla resultante a un proceso deseparación que causa la separación de las partículas de la primera sustancia de la primera y segunda corriente dedisolvente, caracterizado porque: la primera formulación se pone en contacto inicialmente con la primera corriente de disolvente para formar unamezcla de la primera formulación y de la primera corriente de disolvente, y la mezcla de la primera formulación y dela primera corriente de disolvente entonces se pone en contacto a continuación con la segunda corriente dedisolvente.
