    • In a process for separating mixtures of partially fluorinated or perfluorinated hydrocarbon compounds which possibly contain other chain members from the group of heteroatoms: nitrogen, oxygen, boron, phosphorus and sulphur and/or can be substituted by other halogen atoms, those partially or perfluorinated compounds which have an acyclic, straight-chain structure and a critical molecular diameter between 4 and 7 ANGSTROM or are substituted by residues having a straight-chain, acyclic structure and a critical molecular diameter between 4 and 7 ANGSTROM , are separated from the partially or perfluorinated compounds which do not contain straight-chain, acyclic residues and which have a critical molecular diameter at least 1.1 times that of said straight-chain, acyclic residues, in liquid or gaseous phase. The mixture or a solution of the mixture in an inert organic solvent having a molecular diameter greater than that of said straight-chain, acyclic residues is placed in contact with a quantity of a molecular sieve sufficient for adsorption. The mean open pore diameter of the molecular sieve is in the range of the critical molecular diameter of the above-mentioned acyclic, straight-chain residues or up to 30 % less. The molecular sieve laden principally with the compounds containing acyclic residues is separated and the compounds adsorbed on the molecular sieve are desorbed.
    • 在可以含有其它链成员的杂原子组中分离出部分氟化或全氟化烃化合物的混合物的方法中:氮,氧,硼,磷和硫,和/或可被其它卤素原子取代,部分或全氟化合物 其具有非循环的直链结构和4至7个ANGSTROM的临界分子直径或被具有直链,无环结构和4至7个ANGSTROM之间的临界分子直径的残基所取代,被部分或全氟化 不含直链,非环状残基的化合物,其在液相或气相中的临界分子直径至少为所述直链无环残基的1.1倍。 将混合物或其混合物在具有大于所述直链无环残基的分子直径的惰性有机溶剂中的溶液与一定量的足以吸附的分子筛接触。 分子筛的平均开孔直径在上述无环,直链残基的临界分子直径的范围内,或低至少30%。 分离出主要含有无环残基的化合物的分子筛,吸附在分子筛上的化合物被解吸。
