Title (EN) SURFACTANT SYSTEMS FOR CRYSTALLIZATION OF ORGANIC COMPOUNDS
(FR) SYSTÈMES TENSIOACTIFS POUR LA CRISTALLISATION DE COMPOSÉS ORGANIQUES
Abstract: front page image
(EN)The present invention is directed to methods for producing crystals or aggregates of organic compounds using a composition comprising a surfactant-water mixture, the organic compound and optionally an organic solvent as starting composition. This surfactant system enables the production of a high variety of different crystals and aggregates. The method is in particular suitable for obtaining crystals and aggregates optimized for isolation and purification during chemical synthesis processes.
(FR)La présente invention concerne des procédés de production de cristaux ou d'agrégats de composés organiques à l'aide d'une composition comprenant un mélange tensioactif-eau, le composé organique et éventuellement un solvant organique en tant que composition de départ. Ce système tensioactif permet la production d'une grande variété de cristaux et d'agrégats différents. Le procédé est en particulier approprié pour obtenir des cristaux et des agrégats optimisés pour l'isolation et la purification pendant des processus de synthèse chimique.
