| Abstract: | In this paper,high purity sucrose octaacetate(SOA) was prepared by recrystallization.The parameters of recrystallization including the solvents,times and speed of crystallization which affected the purity and crystal morphology of SOA were also discussed.Gas chromatograph-mass spectrometer(GC-MS),scanning electron microscope(SEM) and X-ray diffraction microscope were performed to characterize SOA,and the results demonstrated that the purity was more than 99.7% which satisfied the desired requirements. |
