Abstract

Oppfinnelsen innbefatter en fremgangsmåte for fremstilling av partikler med jevn størrelse fra faste forbindelser. Først blir en egnet fast forbindelse oppløst i et egnet løs-ningsmiddel. Derpå blir en ut-fellingsvæske tilført under utfelling av ikke-aggregerte partikler med i det vesentlige jevn middeldiameter. Partik-lene blir deretter separert fra løs-ningsmidlet. Avhengig av den faste forbindelse og den ønskede partikkelstør-relse kan parametrene temperatur, for-hold mellom ikke-løsningsmiddel og løs-ningsmiddel, tilførselshastighet, om-røringshastighet og volum varieres i overensstemmelse med oppfinnelsen. Ut-fellingsvæsken kan være vandig eller ikke-vandig i avhengighet av forbindel-sens relative oppløselighet og den ønskede suspenderende bærer.The invention includes a process for the preparation of uniformly sized particles from solid compounds. First, a suitable solid compound is dissolved in a suitable solvent. Then a precipitating liquid is supplied during precipitation of non-aggregated particles with a substantially uniform average diameter. The particles are then separated from the solvent. Depending on the solid compound and the desired particle size, the parameters temperature, non-solvent to solvent ratio, feed rate, agitation rate and volume can be varied in accordance with the invention. The precipitating liquid may be aqueous or non-aqueous depending on the relative solubility of the compound and the desired suspending carrier.
