Title (EN) PROCESS FOR THE PREPARATION OF A MIXTURE OF CHELATING AGENTS, MIXTURE OF CHELATING AGENTS AND METHODS OF USING THEM
(FR) PROCÉDÉ DE PRÉPARATION D'UN MÉLANGE D'AGENTS CHÉLATANTS, MÉLANGE D'AGENTS CHÉLATANTS ET PROCÉDÉS D'UTILISATION DE CEUX-CI
Abstract:
(EN) The present invention relates to a process for the in situ preparation of mixtures of chelating agents by catalyzed reactions of diethanolamine with maleic acid and then with 2-halocarboxylic acid, mixtures obtainable using said process and mixtures of chelating agents. In addition, the invention relates to methods where such mixtures are used.
(FR) La présente invention concerne un procédé de préparation in situ de mélanges d'agents chélatants par des réactions catalysées de diéthanolamine avec de l'acide maléique puis avec de l'acide 2-halocarboxylique, l'invention concerne également des mélanges pouvant être obtenus à l'aide dudit procédé et des mélanges d'agents chélatants. L'invention concerne en outre des procédés d'utilisation de ces mélanges.
