Abstract
Aim To synthesize 1,3-diphenylpropane-1,3-dione and study its molecule structure and thermal properties.Methods 1,3-diphenylpropane-1,3-dione was synthesized by ethyl benzoate and acetophenone as raw materials and its structure was characterized by 1H NMR,ESI-MS,IR and UV-Vis spectra.The thermal properties of 1,3-diphenylpropane-1,3-dione were studied by TG-DSC methods in the static air.Results The product's molecule structure was characterized by a series of spectrum.From 134 ℃ to 308 ℃,a mass loss of 93.21% was observed.From 309 ℃ to 392 ℃,a mass loss of 6.61% was observed.The two peaks at 249 ℃ and 365 ℃ in DTG were observed by exothermic decomposed reaction respectively.Conclusion It was indicated that 1,3-diphenylpropane-1,3-dione is stable in solid and liquid by TG-DSC.
