Thermal behavior of loratadine
Simultaneous thermogravimetry (TG) and differential thermal analysis (DTA) techniques were used for the characterization the thermal degradation of loratadine, ethyl-4-(8-chloro-5,6-dihydro-11H-benzo[5,6]cyclohepta[1,2-b]pyridin-11-yli dine)-1-piperidinecarboxylate. TG analysis revealed that the the...

| description | Simultaneous thermogravimetry (TG) and differential thermal analysis (DTA) techniques were used for the characterization the thermal degradation of loratadine, ethyl-4-(8-chloro-5,6-dihydro-11H-benzo[5,6]cyclohepta[1,2-b]pyridin-11-yli dine)-1-piperidinecarboxylate. TG analysis revealed that the thermal decomposition occurs in one step in the 200-400 deg C range in nitrogen atmosphere. DTA and DSC curves showed that loratadine melts before the decomposition and the decomposition products are volatile in nitrogen. In air the decomposition follows very similar profile up to 300 deg C, but two exothermic events are observed in the 170-680 deg C temperature range. |
