Title:
METHOD OF STORING GROUP VIII METAL-ORGANOPHOSPHITE COMPLEX CATALYST SOLUTION
Document Type and Number:
WIPO Patent Application WO/2004/052539
Kind Code:
A1
Abstract:
A method of storing a catalyst solution containing a free phosphite ligand and a Group VIII metal-organophosphite complex catalyst, in which the deterioration of phosphite compound is inhibited to thereby enable stably storing the catalyst solution for a prolonged period of time. In particular, a method of storing a Group VIII metal-organophosphite complex catalyst solution, characterized in that a catalyst solution containing a free organophosphite ligand and a Group VIII metal-organophosphite complex catalyst is stored in an atmosphere wherein the partial pressure of oxygen is 10 Pa or below; and a method of storing a Group VIII metal-organophosphite complex catalyst solution, characterized in that a hydroformylation catalyst solution containing a free organophosphite ligand and a Group VIII metal-organophosphite complex catalyst is withdrawn from a reaction vessel and stored in a storage container wherein the partial pressure of oxygen in gas phase components is 10 Pa or below.
