  • METHODS FOR PURIFYING ISAVUCONAZONIUM SULFATE
    Publication number: 20210323959
    Abstract: The invention provides methods for purifying isavuconazonium sulfate comprising the steps of —(a) providing a mixture comprising the sulfate salt of the compound of formula (I) and an aliphatic alcohol, wherein the pH of the mixture is in the range of about pH 1 to about pH 6; —(b) allowing a first portion of the sulfate salt of the compound of formula (I) to crystalize from the mixture; and —(c) adding an aprotic organic solvent to the mixture and allowing an additional portion of the sulfate salt of the compound of formula (I) to precipitate from the mixture.

  • Energy input during agglomeration for magnetic separation
    Patent number: 10799881
    Abstract: Method for separating first type particles from a mixture of at least first type particles and second type particles, the method comprising contacting in a dispersion medium first type particles and second type particles with magnet type particles, so that in the dispersion medium first type particles agglomerate to magnet type particles to obtain magnetic agglomerates, separating magnetic agglomerates from second type particles by applying a magnetic field; wherein during step an amount of energy is transferred into a mixture of the dispersion medium, first type particles, second type particles and magnet type particles.
