MEHTOD OF POLYOXYALKYLENEDIAMINE

摘要

injecting H2 gas with polyoxyalkylene acrylonitrile into the reaction vessel at 20-70 atmospheres of H2 gas where the pressure before the injector is 2-10 higher than the pressure of H2 gas; hydrogeneration-reating at 100-200 deg.C. The polyoxyalkylene acrylonitrile is polyoxyethylene acrylonitrile or polyoxypropylene acrylonitrile. By the process, the reation time is shorter, and the yield is improved and the amt. of primary amine in the obtd. polyoxyalkylene diame is higher.
