(FR) AGGLOMERATS OBTENUS PAR CRISTALLISATION
Abstract
(EN)
The present invention describes novel agglomerates in crystalline form of $g(b)-lactam compounds. Furthermore, a process for the preparation of said agglomerates, wherein a solution or suspension of at least one $g(b)-lactam compound in a solvent is mixed with one or more anti-solvents has been described.
(FR)
L'invention concerne des agglomérats cristallins de composés de bêta-lactamines, ainsi qu'un procédé d'élaboration correspondant: une solution ou une suspension d'au moins un composé de bêta-lactamine dans un solvant est mélangée avec un ou plusieurs anti-solvants.
