Claim:
1. A method of preparing a polyetheramine compound, including a step of bringing a polyether derivative into contact with an amine compound, in the presence of hydrogen and a three-component catalyst for reductive amination-reaction consisting of cobalt oxide, scandium oxide and palladium oxide as active components, wherein the polyether derivative is a polyoxyalkylene compound represented by the following Chemical Formula 2, Chemical Formula 3 or chemical formula 4: in Chemical formula 2 to 4, L R n is an integer of 1 to 500, a and b are independently an integer of 1 to 500, and y is an integer of 2 to 500, and (x+z) is an integer of 2 to 100.
