  • Method for producing crystals from solutions
    Patent number: 6616847
    Abstract: The invention relates to a method for producing crystals from thermally sensitive solids. According to this method, the solid is dissolved in at least one solvent and the solution is concentrated by drawing off the solvent to beyond the saturation concentration of the solid, so that crystallized solids are formed. The solvent is caused to permeate a substantially semi-permeable membrane, preferably by being subjected to excess pressure. The inventive method can be carried out substantially isothermally in order to prevent the thermally sensitive crystals from being damaged.
