    摘要： An aromatic solution of the compound CuAl(CN)Cl.sub.3 alone or with additional solid CuAl(CN)Cl.sub.3 is used for the separation of some unsaturated compound (olefin, acetylene or carbon monoxide) from a feedstream.The feedstream is contacted with the solvent to form a complex of the ligand (olefin, acetylene or carbon monoxide). The feedstream is then separated from the solvent. The solvent is then treated with some combination of heat and lowered pressure to separate the ligand from the solvent. The ligand poor solvent is then recycled to contact fresh feedstream.

    摘要： A process for the separation and recovery of unsaturated aliphatic hydrocarbons from admixture with saturated aliphatic hydrocarbons which comprises contacting such a mixture with a complexing agent comprising cuprous salts of sulfonic acids and dialkyl phosphates under such conditions that the unsaturated hydrocarbons are preferentially complexed with the cuprous salts. In one embodiment, olefins are separated from paraffins by using a cuprous sulfonate dissolved in an aromatic solvent to form a complex with the olefin. The olefin can be separated from the resulting complex and the cuprous salt recycled for reuse.

    摘要： Catalytically-inactive liquid sorbents that comprise bimetallic salt complexes having the generic formula MIMIIXn.Aromatic, wherein MI is a Group I-B metal, MII is a Group III-A metal, X is halogen, n is the sum of the valences of MI and MII, and Aromatic is a monocyclic aromatic hydrocarbon having 6 to 12 carbon atoms are obtained by reacting a MI halide with at least an equivalent amount of a MII halide in an aromatic hydrocarbon to form a sorbent containing said bimetallic salt complex and maintaining said sorbent at a temperature between about 20*C. and the boiling point of the aromatic hydrocarbon while passing a stream of an inert gas through it until the gas leaving the sorbent contains neither MII halide or hydrogen halide.

    摘要： A PROCESS IS DESCRIBED FOR SEPARATING AND RECOVERING COMPLEXIBLE LIQUIDS FROM FEEDSTREAMS CONTAINING THEM, COMPRISING THE STEPS OF COMPLEXING THE LIGANDS WITH A COMPLEXING SOLUTION, STRIPPING IMPURTIES OUT OF SOLUTION, DECOMPLEXING BY FLASHING AT PRESSURES OF FROM 1 ATMOSPHERE TO ABOUT 40 ATMOSPHERES, RECYCLING SOLVENT TO THE

    COMPLEXER AND THEREAFTER RECOVERING SAID LIGANDS AS A HIGH PURITY PRODUCT. THE COMPLEXING SOLUTION COMPRISES GROUP I-B METAL SALTS DISSOLVED IN LOW VOLATILITY AROMATIC SOLVENTS. THE LIGANDS ARE DECOMPLEXED BY EITHER FLASHING OFF A HIGH PRESSURES OR BY MULTIPLE STAGE FLASHING.
