Preparation of disazo condensation pigments in microreactors |
摘要 |
A process for preparing disazo condensation pigments by diazotization of an aromatic amine, azo coupling with a coupling component to form an azocarboxylic acid or azodicarboxylic acid, formation of an azocarbonyl chloride or azodicarbonyl dichloride and condensation of the azocarbonyl chloride with an aromatic diamine or of the azodicarbonyl dichloride with an aromatic amine comprises effecting the acyl chloride formation and/or the condensation and optionally the diazotization and optionally the azo coupling in a microreactor.
