Title (EN) QUATERNARY CARBOXYLATE COMPOSITIONS FOR EXTRACTING C1 TO C4 CARBOXYLIC ACIDS FROM AQUEOUS STREAMS
(FR) COMPOSITIONS DE CARBOXYLATE QUATERNAIRE POUR L'EXTRACTION D'ACIDES CARBOXYLIQUES EN C1 À C4 DE FLUX AQUEUX
Abstract: front page image
(EN)This invention relates to solvents for extracting C1 to C4 carboxylic acids from aqueous streams. More specifically, the extraction solvents include one or more salts composed of a tetraalkylphosphonium cation and a carboxylate anion. The extraction solvents may further include one or more non-ionic liquid organic solvents as an enhancer. The extraction solvents are useful for extracting aqueous mixtures containing one or more lower carboxylic acids, such as monocarboxylic acids, alkoxycarboxylic acids, and halogen-containing carboxylic acids.
(FR)L'invention concerne des solvants pour l'extraction d'acides carboxyliques en C1 à C4 de flux aqueux. Plus particulièrement, les solvants d'extraction comprennent un ou plusieurs sels composés d'un cation de tétraalkylphosphonium et d'un anion carboxylate. Les solvants d'extraction peuvent en outre comprendre un ou plusieurs solvants organiques liquides non ioniques en tant qu'activateur. Les solvants d'extraction sont utiles pour extraire des mélanges aqueux contenant un ou plusieurs acides carboxyliques inférieurs, tels que des acides monocarboxyliques, des acides alcoxycarboxyliques et des acides carboxyliques contenant halogène.
