Patent number: 4442297Abstract: There are disclosed manganese compounds of the formulaMn.sup.II LX.sub.2 (Q).sub.n (I)wherein L is a monodentate ligand of the formulaPR.sup.1 R.sup.2 R.sup.3 (II)wherein R.sup.1, R.sup.2, and R.sup.3 are identical or different and are substituted or unsubstituted alkyl, cycloalkyl, alkenyl, alkynyl, or aryl; or hydrogen providing that no more than two of the R.sup.1, R.sup.2, and R.sup.3 groups are substituted or unsubstituted aryl groups and that at least one of R.sup.1, R.sup.2, and R.sup.3 is a substituted or unsubstituted alkyl, cycloalkyl, alkenyl, alkynyl, or aryl group,X is a species capable of existing as an anion, e.g., Cl, Br,Q is a solvento molecule capable of forming a chemical bond to the manganese, andn is 1, 2, or 3 solvent donor atoms.The manganese compounds are useful in the separation of a gas such as oxygen, hydrogen, sulfur dioxide, an alkene, and carbon monoxide from fluids containing these gases.Type: GrantFiled: May 11, 1981Date of Patent: April 10, 1984Assignee: Facilitated Separations, Inc.Inventors: William E. Hill, Charles A. McAuliffe

Patent number: 4363765Abstract: A particular process is provided for the recovery of rhodium values from liquid compositions. The process comprises contacting a solubilized rhodium complex with water, a crown ether and an alkaline cesium salt in the liquid phase such that a solid comprising rhodium is formed. The process is applied with particular advantage to the recovery of solubilized rhodium values derived from processes for the production of polyhydric alcohols such as ethylene glycol, and monohydric alcohols such as methanol, by the reaction of carbon monoxide and hydrogen in the presence of rhodium carbonyl complex catalysts in a homogeneous liquid medium. The invention also concerns cesium/crown ether salts of anionic rhodium complexes.Type: GrantFiled: April 3, 1981Date of Patent: December 14, 1982Assignee: Union Carbide CorporationInventors: Rocco A. Fiato, Jose' L. Vidal
