Process for the separation of diene from organic mixtures |
| abstract |
Dienes are separated from organic mixtures comprising diene and alkene having one double bond by contacting the mixture against one side of a membrane which is a halogenated polymer of ethylene 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. Exemplary of the membranes are polyvinylchloride and tetrafluoroethylene/ethylene copolymer. |
