At a temperature of 80oC100oC serves a mixture of propylene oxide and ethylene oxide, after which the mass is maintained at a temperature of 105 5oC for two hours under TR 2.09-058-90.Waste Polyoxypropylenediamine formed with phosphate sorption purification of alkaline polymerizate Polyoxypropylenediamine. In the reactor-mixer download demineralized water in an amount of 5 to 7.7% by weight of prepolymerisation nitrogen perelavlivaet in the reactor-mixer alkaline polymerizat and stir the whole mass at a temperature of 855oC for one hour, from the hopper load bentonite in the amount of 0.15oC0,5% by weight of alkaline polymerizate. After half an hour of stirring the whole mass is fed to a filter press and purified Polyoxypropylenediamine perelavlivaet nitrogen into the container for storage. Waste Polyoxypropylenediamine unloaded into a container and taken on samoatel.Waste Polyoxypropylenediamine according to TR 2.09-058-90 have the following composition,
