ABSTRACT:
Iron nitrosyl carbonyl catalyst is prepared by dissolving impure iron nitrosyl carbonyl in a solvent solution, then adding sufficient miscible non-solvent to the solution to result in separation of the mixture into an upper layer and a lower layer containing iron nitrosyl carbonyl. Preferably, the solvent is used in preparation of the iron nitrosyl carbonyl, and the solution is, therefore, the product of the preparation. The miscible non-solvent is added to the product solution to effect separation of layers for isolation of purified iron nitrosyl carbonyl product.
