Starch acetates(SA) with different degrees of substitution were synthesized by reaction of corn starch and acetic acid/acetic anhydride catalyzed with concentrated.H₂SO₄.By means of FTIR,SEM,DSC,TGA and XRD,we studied the microstructure,particle shape,meltage temperature,decomposition temperature and crystal degree,and gained better understanding about influences of different degrees of substitution on microstructure and thermal property of starch acetates.With concentrated sulfuric acid as catalyst instead of methyl sulfuric acid,optimal reaction conditions are: refluxing temperature is in the range of 75~80℃, reaction time is 3 h with 0.38 mL of concentrate sulfuric acid.With the increasing of degree of substitution,the crystallinity of the starch acetate decreased from 37.95% to 0,T_d increased from 327.32℃ to 381.35℃.
