Proposed structures for substances released during the 2nd decomposition stage. Starting with dibenzazepine (60) (“iminostilbene”) adsorbed on activated carbon strongly differing products are formed. Boxes support categorisation of substances which are specific for the activated carbons SAE Super or HK 950 as well as substances dominating in clustering groups (Fig. 7a). The red dashed box emphasizes decomposition products which are released at low carbamazepine loadings. The gray box on the bottom indicates substances that were released only at high loadings investigated on the SAE Super.
