SEPARATION OF DICARBOXYLIC ACID

Mixtures of dicarboxylic acids are separated by subjecting an aqueous solution of the mixtures to membrane filtration, in which the pH of the solution is adjusted to such a value that the membrane is permeable to less than 5 % of the amount of substance used, relative to at least one component of th...
