titleOfInvention | Process for preparing solutions of n-methylmorpholinoxide with a low content of nitrosomorpholine |
abstract | A method of preparing N-methylmorpholinoxide by oxidising N-methylmorpholine in an aqueous hydrogen peroxide solution at a temperature of 55 to 75 degrees C with a molar ratio of H2O2/amine=0.4 to 0.9, preferably 0.5 to 0.70 possibly in the presence of chelating reagents, possibly in the presence of CO2, with distilling off of unprecipitated N-methylmorpholine under reduced pressure. After adding hydrogen peroxide to the reaction mix and after a decrease in its concentration to 0.05 to 0.15 % of mass, 0.01 to 0.05 % of mass of hydrazine is added, calculated to the reaction mix, and the mixture is kept at reaction temperature for a further half to three hours. |
