| titleOfInvention | Recovery of chemical components of cellulosic regenerating solution |
| abstract | Recovery of the chemical components of a cellulosic organic solvent regenerating solution containing a dialkylacylamide, a lower aliphatic monohydric alcohol, a nitrite of the alcohol and nitric acid. The process comprises distilling the solution to remove the alcohol nitrite and alcohol, leaving the dialkylacylamide and nitric acid, recovering the alcohol, hydrolyzing to convert the alcohol nitrite to the alcohol and nitrous acid, neutralizing the nitric and nitrous acid with an alkali or alkaline earth metal oxide or hydroxide and distilling the solution to remove water and to separate and recover the remaining alcohol, the dialkylacylamide and the nitrate and nitrite salts. The nitrite and nitrate salts are converted by pyrolysis to nitrogen dioxide. The process results in substantially total recovery of the process chemicals. |
