Thermal decomposition of some chemotherapic substances
Abstract
Thermogravimetry, derivative thermogravimetry (TG, DTG), differential scanning calorimetry (DSC) and X ray diffraction powder patterns have been used to study trimethoprim, sulfamethoxazole, ampicillim, tetracycline hydrochloride and rifampim. The results revealed the extent of their thermal stability and also allowed interpretations concerning their thermal decompositions in air atmosphere.
