Methods for making active crystalline materials |
摘要 |
The present invention relates to an active crystalline material, especially an active multicomponent crystalline material such as a salt or a cocrystal, which may be made by dispersing precursor components of the active crystalline material in a liquid medium which comprises an anti-solvent, maintaining the dispersion for a period during which the active crystalline material is formed, and, during said period, exposing the dispersion to a solvent, which solvent being present in the liquid medium in a minor proportion by weight thereof. |

1. A method for making an active crystalline material, the method comprising:
dispersing precursor components of the active crystalline material in a liquid medium comprising an anti-solvent to generate a dispersion; maintaining the dispersion for a period sufficient to form the active crystalline material; and exposing the dispersion to a solvent, where the solvent is present in the liquid medium in a minor proportion by weight thereof. |
