Abstract
Organometallic compounds and/or metal carbonyls are separated from their solutions in organic media with the aid of semi-permeable membranes made of aromatic polyamides.
Claims49
A process for concentrating solutions of organometallic compounds and/or metal carbonyls in an organic media by ultrafiltration or dialysis, said process comprising contacting said solutions with a semi-permeable polyaramide membrane having a retention side and a permeation side opposite said retention side, said membrane being permeable only to said organic media.
A process for concentrating solutions of non-dissociable organometallic complexes and/or metal carbonyl complexes and excess ligands in an organic media by ultrafiltration or dialysis, said process comprising contacting said solutions with a semi-permeable polyaramide membrane having a retention side and a permeation side opposite said retention side, said membrane being permeable only to said organic media.
