(EN) PROCESS FOR PREPARING BECLOMETHASONE DIPROPIONATE FREON$m(3) CLATHRATE
(FR) PROCEDE DE PREPARATION DE CLATHRATE DE FREON$m(3) DE DIPROPIONATE DE BECLOMETHASONE
Abstract
(EN)
Described is a process for preparing beclomethasone dipropionate Freon$m(3) clathrate comprising the use of an agent which selectively binds methanol to selectively remove methanol from a mixture of methanol and Freon$m(3) 11 containing beclomethasone dipropionate.
(FR)
L'invention concerne un procédé de préparation de clathrate de Fréon$m(3) de dipropionate de béclométhasone consistant à utiliser un agent de liaison sélective avec le méthanol, afin de supprimer sélectivement le méthanol d'un mélange de méthanol et de Fréon$m(3) 11 contenant du dipropionate de béclométhasone.
