Abstract:
PCT No. PCT/DE90/00658 Sec. 371 Date Feb. 28, 1992 Sec. 102(e) Date Feb. 28, 1992 PCT Filed Aug. 28, 1990 PCT Pub. No. WO91/03442 PCT Pub. Date Mar. 21, 1991.A process for separation of mixtures of partially- or perfluorinated hydrocarbon compounds, which optionally contain additional chain members from the heteroatom group nitrogen, oxygen, boron, phosphorus and sulfur and/or can be substituted by further halogen atoms, characterized in that such partially- or perfluorinated compounds, which have an acyclic straight-chain structure and a critical molecule diameter in the range from 4 to 7 ANGSTROM or are substituted by residues with a straight-chain acyclic structure and with a critical molecule diameter in the range from 4 to 7 ANGSTROM , of such partially- or perfluorinated compounds, which have no straight-chain acyclic residues, and whose critical molecule diameter amounts to at least 1.1-fold times the that of the aforementioned straight-chain acyclic residues, in liquid or gaseous phase are separated in that a mixture or a solution of the mixture in an inert organic solvent, the molecular diameter of which is larger that of the aforementioned straight-chain acyclic residue, is contacted with an amount of a molecular sieve sufficient for adsorption, the average pore diameter of which lies in the range of the critical molecule diameter of the aforesaid acyclic residue or up to 30% less, separating the molecular sieve laden predominantly with compounds containing acyclic residues, and desorbing the compounds adsorbed on the molecular sieve.
