Abstract
In this paper,3,4-diacetylhexane-2,5-dione was synthesized from acetylacetone and iodine.Its molecule structure was characterized by 1HNMR,MS,IR and UV-Vis spectra.The thermal properties of 3,4-diacetylhexane-2,5-dione were studied based on the TG-DTG and DSC analyses in a static air atmosphere.In a temperature range of 81~165 ℃,a mass loss of 100% was reported.The maximum peak at 153 ℃ in DTG was observed by exothermic decomposition reaction.The maximum peak at 197 ℃ in DSC was observed by endothermic reaction.
