ABSTRACT:
A reaction vessel (10) includes a housing (12) having an interior cavity (14). Water insoluble reaction substances (16,16') are contained within the cavity (14) for producing a water soluble product from reacting with a water soluble precursor. A composite membrane defines at least a portion of the housing (12) for selectively imbibing the water soluble precursor therethrough into the housing (12) for reaction with the reaction substances (16,16'), imbibing of the product therethrough out of the housing (12) and being impermeable to the reaction substances (16,16') for maintaining the reaction substances (16,16') within the cavity.
