MANUFACTURING METHOD OF AMINOPROPOXY-POLYOXYALKYLENE CAPABLE OF MANUFACTURING CYANOETHYLATED POLYPROPYLENE GLYCOL AND 3-1 AMINOPROPOXY-POLYOXYPROPYLENE

摘要

PURPOSE: A manufacturing method of aminopropoxy-polyoxyalkylene is provided to increase the yield of cyanoethylated polyoxyalkylene, and to remarkably increase the yield of 3-1 aminopropoxy-polyoxyalkylene.;CONSTITUTION: A manufacturing method of aminopropoxy-polyoxyalkylene comprises: a cyanoethylation step using KOH or NaOH solution at 20-70 Cfor preparing cyanoethylated polyoxyalkylene of which has a -CN terminal group by substituting an OH group which is a terminal group of a polyoxyalkylene; a cyanoethylation step for manufacturing cyanoethylated polyoxyalkylene which has a -CN terminal end; and a hydrogenation step for adding hydrogen under the condition of 80-200 C and 5-170 bar by adding a nickel catalyst additive into the cyanoethylated polyoxyalkylene.;COPYRIGHT KIPO 2013
