摘要： The invention concerns a process for the continuous treatment of an emulsion and/or a micro-emulsion assisted by an “expanded liquid” for the production of micro- and/or nano-particles or micro- and/or nano-spheres containing one or more active ingredients. In particular, a liquid solvent expanded by compressed or supercritical CO2 is contacted with an O/W emulsion, or alternatively a W/O emulsion or multiple emulsions, formed by an external phase that is itself a liquid expanded by compressed CO2. The expanded liquid forms a solution with the dispersed phase of the emulsion and extracts it inducing the formation of the desired particles of the dissolved compounds.The process is carried out in a counter-current packed column wherein the expanded emulsion is fed from the top, while the expanded liquid is fed from the bottom. Thanks to the presence of the expanded liquid, any deposition of the solid particles produced on the packing elements is avoided, thus preventing any column blockage. A suspension of micro-structured particles of the desired product can be collected continuously at the bottom of the column.

摘要： The present invention provides methods and devices for producing particles with an average diameter less than about 15 μm using the precipitation with compressed fluid-antisolvent (PCA) process and the carbon-dioxide assisted nebulization with a bubble dryer (CAN-BD) process. In the methods and nozzles of the invention, at least one jet of supercritical or near-supercritical fluid and at least one jet of solution interact to mix the supercritical or near-supercritical fluid and the solution within a chamber. The solution contains at least one solvent and at least one solute. At least one of the jets is a swirling jet. To form particles, the solvent and supercritical or near-supercritical fluid are then injected into a PCA or a CAN-BD process chamber. The degree of mixing depends in part on the power input into the mixing chamber. Power inputs of about 6.5×109 W/m3 enhance the degree of mixing and allow production of nanoscale particles with the PCA process. The nanoscale particles have a size distribution so that polydispersity is less than about 1.75.
