Synthesis,Molecular Structure and Thermal Stability of Percarbamide
Abstract:
The method of four factors and three levels was used to study the influence of the material ratio,reaction temperature, reaction time and stabilizer in order to obtain the optimal process condition of percarbamide. The results show that the yield of percarbamide is 99%,and the oxygen content is 17.5% under the optimmal synthetic condition. The thermal stability of percarbamide was investigated by thermal analysis. The results show that the content of oxygen and percarbamide decreases rapidly when the temperature exceeds 65℃. Finally,the crystal structure was determined by X-ray diffraction,and the software,Diamond,was used to describe the three-dimensional supramolecular structure of percarbamide and the connection mode of hydrogen bond.
