Title (EN) PROCESS FOR PREPARING BOSCALID
(FR) PROCÉDÉ DE PRÉPARATION DE BOSCALIDE
Abstract: front page image
(EN) A process for preparing the crystalline modification II of the anhydrate of boscalid is provided, the process comprising providing a solution of boscalid in an organic solvent system, heating the solution to an elevated temperature, and precipitating solid boscalid from the solution, the elevated temperature being sufficient to preferentially form the crystalline modification II of the anhydrate of boscalid.
(FR) L'invention concerne un procédé pour la préparation de la modification cristalline II de l'anhydrate de boscalide, le procédé inclus la fourniture d'une solution de boscalide dans un système de solvant organique, le chauffage de la solution à une température élevée, et la précipitation du boscalide solide à partir de la solution, la température élevée étant suffisante pour former préférentiellement la modification cristalline II de l'anhydrate de boscalide.
