Patent ID: 8895784

Claim:
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 catalyst for reductive amination-reaction including cobalt and yttrium as active components, wherein the polyether derivative is a polyoxyalkylene compound represented by the following Chemical Formula: wherein, X is a single bond or -(L 5 -L 6 -O) c —, L 1 to L 6 are independently a C 1 -C 10 alkylene, a C 2 -C 10 alkenylene, a C 2 -C 10 alkynylene, a C 3 -C 10 cycloalkylene, or a C 6 -C 10 arylene, R 1 is hydrogen, a C 1 -C 18 alkyl group, an un-substituted C 6 -C 30 aryl group, or a C 6 -C 30 aryl group substituted by a C 1 -C 18 alkyl group, a and b are independently an integer of 1 to 500, and c is an integer of 2 to 500.
