Title (EN) REVERSE OSMOSIS MEMBRANE
(FR) MEMBRANE D"OSMOSE INVERSE
Abstract: front page image
(EN)A composite permselective membrane is prepared by reaction of a film or layer containing cycloaliphatic polyfunctional secondary amines with a triacyl halide or its mixture with a diacyl halide. The membrane is useful in separating components of fluid mixtures or solutions, such as the removal of salts from aqueous solutions by reverse osmosis.
(FR)Une membrane composite semi-permeable est preparee par reaction d"un film ou couche contenant des amines cycloaliphatiques polyfonctionnelles avec un halogenure de triacyle ou un melange avec un halogenure de diacyle. La membrane est utile pour la separation de composants de melanges fluides ou de solutions, par exemple pour l"elimination de sels de solutions aqueuses par osmose inverse.
