Olefin complexing reagents comprising Cu(I) carboxylate/BF.sub.3 adducts in aromatic solvents and a method of preparation therefor, and use of said reagents in the separation of olefins from paraffins are provided.
摘要:
Alkenes, alkynes or mixtures thereof are removed from feedstreams by a process which comprises contacting the feedstream with a solution of a cuprous fluorinated acetylacetone in an organic solvent containing stabilizing agent to remove alkene, alkyne or mixture thereof by forming a first cuprous complex, decomposing the first cuprous complex whereby stabilizing agent replaces alkene or alkyne in the first cuprous complex to form a second cuprous complex, and separating the displaced component. The formation of the second cuprous complex avoids any deposition of copper metal upon heating.
摘要:
In processes in which liquid sorbents that are solutions in an aromatic hydrocarbon or halogenated aromatic hydrocarbon of a bimetallic salt complex having the generic formula M.sub.I M.sub.II X.sub.n.Aromatic, wherein M.sub.I is a Group I-B metal, M.sub.II is a Group III-A metal, X is halogen, n is the sum of the valences of M.sub.I and M.sub.II, and Aromatic is an aromatic hydrocarbon or halogenated aromatic hydrocarbon are used to separate complexible ligand from a gas feedstream that comprises an olefin having 2 or 3 carbon atoms, alkylation of the aromatic hydrocarbon or halogenated aromatic hydrocarbon is inhibited by incorporating in the liquid sorbent a small amount of triphenylboron.

1. THE PROCESS FOR THE RECOVERY OF GROUP I-B METAL HALIDE FROM A LIQUID SORBENT THAT IS A SOLUTION IN AN AROMATIC HYDROCARBON OF A BIMETALLIC SALT COMPLEX HAVING THE 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 THAT COMPRISES CONTACTING THE LIQUID SORBENT WITH ANHYDROUS AMMONIA THEREBY FORMING A REACTION PRODUCT THAT CONSISTS ESSENTIALLY OF SOLID MI HALIDE AND A SOLUTION OF NH3:MII HALIDE IN THE AROMATIC HYDROCARBON, AND SEPARATING THE MI HALIDE FROM SAID REACTION PRODUCT.
摘要:
There is described the separation of carbon monoxide from gaseous mixtures by the combined use of liquid barrier permeation and metal complexing techniques. The liquid barrier is in contact with a semi-permeable film membrane, and the barrier contains complex-forming metal ions in aqueous solution. The metal ions may be, for example, cuprous or other metal ions, and mixtures of these metal ions, with or without other cations, may be used. The separation of carbon monoxide from lower alkanes, e.g., ethane and methane, or hydrogen is of particular interest.
摘要:
Combinations of organic phosphines and organic nitrogen bases help stabilize complexing solutions containing cuprous and silver salts whose anionic components are Lewis acids, said salts being dissolved in aromatic solvents, when the solutions are in the presence of olefins, to prevent side reactions from occurring during olefin complexing processes in which the above complexing solutions are employed.
摘要:
There is described the separation of aliphatically-unsaturated hydrocarbons from mixtures by the combined use of liquid barrier permeation and metal complexing techniques. The liquid barrier is within a hydrophilic film membrane, and the barrier contains complex-forming metal ions in aqueous solution. The metal ions may be, for example, noble metal, nickel, mercurous, cuprous or other metal ions, and mixtures of these metal ions, with or without other cations, may be used. The separation of ethylene from ethane and methane is of particular interest.
摘要:
ACETYLENE REACTS WITH CUPROUS ALUMINUM TETRACHLORIDE UNDER AMBIENT CONDITIONS TO FORM A STABLE COMPLEX THAT IS SOLUBLE IN AROMATIC HYDROCARBONS. SINCE ACETYLENE CAN BE READILY RECOVERED FROM THE, SOLUTIONS CONTAINING THE ACETYLENE-CUPROUS ALUMINUM TETRACHLORIDE ARE USEFUL AS A STORAGE, TRANSPORT, OR REACTION MEDIUM FOR ACETYLENE.
