  • Technologies for removing residual solvent from nalmefene hydrochloride and producing crystalline nalmefene hydrochloride monohydrate, monosolvate, or crystalline nalmefene hydrochloride dihydrate
    Patent number: 10927121
    Abstract: Methods for removing residual solvent from Nalmefene Hydrochloride (HCl) and producing crystalline Nalmefene HCl monohydrate, monosolvate or crystalline Nalmefene HCl dihydrate are described. In embodiments, the methods include recrystallizing Nalmefene HCl from a solvate that includes Nalmefene HCl, water, and a first solvent, wherein the first solvent has a molar volume of at least 98 cm3. Crystalline Nalmefene HCl with a desirably low amount of residual solvent is also described.

  • Fluoride-based luminescent phosphors
    Patent number: 9388054
    Abstract: The present disclosure relates to luminescent phosphors and more particularly, to fluoride-based luminescent phosphors, and methods for their preparation in deep eutectic solvent (DES) systems. The luminescent phosphors are formed with accompanying particle size control, relatively higher crystallinity and relatively higher fluorescence intensity.
