Abstract
Abstract There are disclosed manganese compounds of the formula Mn.sup.II LX.sub.2 (Q).sub.n (I) wherein L is a monodentate ligand of the formula PR.sup.1 R.sup.2 R.sup.3 (II) wherein R 1 , R 2 , and R 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 1 , R 2 , and R 3 groups are substituted or unsubstituted aryl groups and that at least one of R 1 , R 2 , and R 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, and n 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.
