The present paper presents the thermal behaviour of methyl-bambus[6]uril in its anion-free and chlorine-included form. Our study was based on thermogravimetry associated to Fourier-transform infrared spectroscopy and differential scanning calorimetry. The compounds decompose after \(300\,^{\circ }\hbox {C}\) and both forms of this macrocycle, contain four hydration water molecules. The main decomposition products are \(\hbox {H}_2\hbox {O}\), \(\hbox {CO}_2\), \(\hbox {NH}_3\) and isocyanic acid as we could detect by FTIR spectroscopy. Finally, we verified that the caviplex loses its chloride ion after \(270\ ^{\circ }\hbox {C}\) and may produce the anion-free macrocyle upon heating.
