Abstract:
Cuprous organohaloaluminates and cuprous organohaloborates possessing the general formula CuMRX3 wherein M is a boron or aluminum atom, X is a chlorine, bromine or fluorine atom, and R is a monovalent lower alkyl radical, phenyl radical, alkylaryl radical or substituted alkyl phenyl or alkylaryl radical, readily complex with olefins, diolefins, acetylenes, aromatics, carbon monoxide, etc. The cuprous organohaloaluminates and cuprous organohaloborates are employed in the separation and recovery of complexible ligands from feedstreams containing the same. Typically, a feedstream containing a complexible ligand is contacted with a liquid sorbent system comprising the cuprous organohaloaluminate and/or cuprous organohaloborate. The complexible ligands contained in the feedstream complex with the organometal compositions and are ultimately recovered therefrom by a ligand exchange operation generally requiring n-l ligand exchange operations for n complexed complexible ligands to be separated and recovered. The separation in each of the ligand exchange operations is accomplished by contacting the organometal-complexible ligand complex with a stripping ligand that forms a more stable complex with the organometallic material than the complexible ligand or ligands, thereby exchanging the stripping complexible ligand or ligands in the original sorbent complex.
Abstract:
HYDROCARBON COMPOUNDS CAN BE DEMETHYLATED IN THE PRESENCE OF HYDROGEN AND A NOVEL SOLID, REDUCED BIMETALLIC CATALYST PREPARED BY REACTING DIMETHYL OR TRIMETHYL ALUMINUM DERIVATIVES WITH COMPOUNDS OF IRON, COBALT, OR NICKEL. THE REACTION MAY BE UTILIZED TO REMOVE ONE OR MORE METHYL OR METHYLENE GROUPS FROM ALIPHATIC, ALKYL AROMATIC OR ALICYCLIC COMPOUNDS, THEREBY REDUCING THE CARBON NUMBER OF SUCH COMPOUNDS. IN A PREFERRED EMBODIMENT THE REACTION TAKES PLACE AT A REDUCED TEMPERATURE.
Abstract:
A PROCESS FOR PREPARING A CATALYST WHICH CONSISTS ESSENTIALLY OF CONTACING A CARBENE COMPLEX SELECTED FROM THE GROUP CONSISTING OF COMPLEXES HAVING THE FORMULAS
A(M(CO)5COR) AND M(CO)5(COR)R''
WHEREIN A IS A UNIPOSITIVE CATION SLECTED FROM THE GROUP CONSISTING OF LI, NA, K AND CATIONS HAVING THE GENERAL FORMULA J4Q WHEREIN Q IS A GROUP V ELEMENT AND J IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND C1 TO C30 HYDROCARBYL RADICALS, M IS A GROUP VI-B METAL, R AND R'' ARE C1 TO C30 HYDROCARBYL RADICALS, WITH ALY3 OR AN ORGANOMETALLIC HALIDE SELECTED FROM THE GROUP CONSISTING OF COMPOUNDS HAVING THE GENERAL FORMULA R"NDYM WHERE R" IS CHOSEN FROM THE GROUP CONSISTING OF C1 TO C30 HYDROCARBYL RADICALS, D IS A METAL SELECTED FROM THE GROUP CONSISTING OF GROUP II AND GROUP III OF THE PERIODIC TABLE OF THE ELEMENTS, Y IS A HALIDE, AND N IS AN INTERGER OF FROM 1 TO 3 AND M IS AN INTERGER OF FROM 0 TO 3, THEIR TOTAL EQUAL TO THE VALENCE OF D, THE MOLAR RATIO OF ORGANO-METRALLIC HALIDE TO GROUP VI-B METAL BEING FROM ABOUT 0.5:1 AND 50:1, AT A TEMPERATURE OF FROM ABOUT- 100 TO +150*C. AND A PRESSURE OF FROM ABOUT 0.1 TO 1000 ATMOSPHERES, WHEREBY A CATALYST IS FORMED. THE RESULTING CATALYST IS USEFUL FOR DISPROPORTIONATING OLEFINS.
