Process for the purification of quinaldine |
| abstract |
In a process for the purification of quinaldin from thenCoal tar processing is the quinaldine fractionna mononuclear aromatic of the phenol, cresol and xylenol typenadded, with adduct formation with quinaldinencrystallized and the quinaldine / mononuclear aromatic adductnthen separated, taking the quinaldine fractionn5 to 20% by weight of one before the mononuclear aromatic is addednAromatic mixture or toluene, based on the mass of thenQuinaldine fraction. |
