  • Process for the purification of climbazole
    Publication number: 20050107454
    Abstract: The invention relates to a process for the purification of climbazole and to climbazole-containing compositions produced in this way. Starting from a mixture containing climbazole and an organic solvent, climbazole is crystallised and the solvent separated off to obtain a crystal cake. The crystal cake is washed repeatedly with the organic solvent. During crystallising and washing, the crystal cake is freed from the solvent only to the extent that the crystal cake is still completely wetted with the solvent.
