MANUFACTURING METHOD OF AMINO PROPOXY-POLYOXY-ALKYLENE

Title compd. was prepd. by the hydrogenation of 2-cyanoethoxy-polyoxyalkylene (I) in the presence of Ni catalyst. I was obtained by cyanoethylation of polyoxyalkylene (M.W. 7300) having OH group. Thus, 100 g bis (2-cyanoethoxy)-polyoxyethylene (M.W. 7,650, OH 0.05 meq/g, cyano 0.256 meq/g) was hydro...

Summary:Title compd. was prepd. by the hydrogenation of 2-cyanoethoxy-polyoxyalkylene (I) in the presence of Ni catalyst. I was obtained by cyanoethylation of polyoxyalkylene (M.W. 7300) having OH group. Thus, 100 g bis (2-cyanoethoxy)-polyoxyethylene (M.W. 7,650, OH 0.05 meq/g, cyano 0.256 meq/g) was hydrogenated at 150 C, 30-50kg/cm2 for 3 hr in the presence of 2 g Ni catalyst to give bis (3-aminopropoxy)-polyethylene (yield 97.3%).
