The enantiomer separation capacity of heterogeneous cellulose derivatives was evaluated and compared. FTIR spectrum and chemical element analysis results confirmed that cellulose derivatives were successfully synthesized with a high degree of substitution. Cellulose derivatives synthesized by the carbonate aminolysis method have higher enantiomer separation capacity than by the tritylation/detritylation one. The research has contributed to perfecting the tritylation/detritylation and carbonate aminolysis methods regarding synthesizing heterogeneous cellulose derivatives
