Abstract:
AND WITHDRAWING AT THE OTHER SIDE A VAPOROUS MIXTURE HAVING INCREASED DIENE CONCENTRATION. Exemplary of the organic mixtures is a mixture of butadiene and butene.
Dienes are separated from organic mixtures comprising diene and alkene having one double bond by contacting the mixture against one side of a polymeric permeation membrane which is an aromatic imide polymer of the formula
