A process for separating one chiral compound from a mixture of chiral compounds is disclosed. The separation process involves using a chiral stationary phase (CSP) which comprises a chiral organic material deposited on an amorphous silica support having a unimodal distribution of pore sizes in the range of about 300 .ANG. to about 25,000 .ANG. and a surface area of less than about 30 m.sup.2 /g.
