Title (EN) A83543 RECOVERY PROCESS
(FR) PROCEDE POUR LA RECUPERATION DE A83543
Abstract:
(EN) Improved process for recovering the useful insecticidal fermentation product A83543, comprising major components A83543A and A83543D and minor components A83543B, A83543C, A83543E, A983543F, A83543G, A83543H and A83543J, which comprises extracting the A83543 from the whole broth into a water miscible solvent such as acetone, filtering to remove the biomass, raising the pH of the filtrate to 10-11 and extracting the A83543 with an immiscible solvent such as ethyl acetate, back extracting with an acidic solution and separating the A83543 by precipitating it with a base.
(FR) Procédé amélioré pour la récupération d'un produit utile de fermentation d'insecticide A83543, comprenant des composants principaux A83543A et A83543D et des composants secondaires A83543B, A83543C, A83543E, A983543F, A83543G, A83543H et A83543J, qui comprend l'extraction du A83543 de l'ensemble dans un solvant miscible dans l'eau comme de l'acétone, le filtrage pour enlever la biomasse, l'augmentation à 10-11 du pH du produit filtré et l'extraction du A83543 à l'aide d'un solvant immiscible comme de l'acétate d'éthyle, l'extraction à l'arrière avec une solution acide et la séparation du A83543 en le précipitant avec une base.
