Analytical high-performance liquid chromatographic enantioseparation of 1-(4-chlorobenzhydryl) piperazine benzamide derivatives was accomplished on different chiral stationary phases. The enantiomers of the compounds were resolved by normal-phase chromatography on silica-based amylose tris(3,5-dimethylphenylcarbamate) (Chiralpak AD-H), cellulose tris(3,5-dimethylphenylcarbamate) (Chiralcel OD-H) and cellulose tris(4-methylbenzoate) (Chiralcel OJ) columns with mobile phases consisting of mixtures of n-hexane and ethanol in different proportions (90: 10, 80: 20). The mobile phase and the chiral stationary phase were varied to achieve the best resolution. The effect of the concentration of ethanol in the mobile phase was studied. The resolution obtained on the three columns was significant.
