VERFAHREN ZUR BESTIMMUNG DER DIAZONIUM-IONENKONZENTRATION. |
摘要 |
The invention relates to a method of determining and controlling the diazonium ion concentration in diazotization solutions and/or in azo coupling reactions, which comprises determining said diazonium ion concentration by means of IR spectroscopy from the intensity of the N 3BOND N stretching frequency. The method is extremely selective and virtually trouble-free and permits the simultaneous determination of the concentration of different diazonium salts in mixtures. |
