Abstract The thermal decomposition of racemic neoclausenamidone was studied using differential scanning calorimetry and thermogravimetry. Neoclausenamidone decomposed rapidly between 232 ℃ and 335 ℃ in the nitrogen stream with a heating rate of 10 K·min-1. Complete decomposition happened at the temperature up to 475 ℃ ......
