Basic Indole Ring Enantiomer Separation on Cellulose Tris(3,5‐dimethylphenylcarbamate) Coated TiO2/SiO2 Chiral Stationary Phase

Abstract Cellulose tris(3,5‐dimethylphenylcarbamate) (CDMPC) coated TiO2/SiO2 has been prepared by coating CDMPC on TiO2/SiO2 which consists of micrometer‐sized silica spheres as core and nanometer‐sized titania particles as surface coating. Eight basic indole ring derivative enantiomers were separated on this CDMPC coated CSP and symmetrical peaks were obtained using hexane as the mobile phase and various alcohols as modifiers. The influence of the mobile phase composition and structural variation of the solutes on the enantioseparation was investigated and discussed.
