Abstract:
A chiral stationary phase represented by: ##STR5## where carrier represents a refractory inorganic oxide having bound surface hydroxyl groups, O--Si is the covalent bond between the bound surface hydroxyl groups of said refractory inorganic oxide and silicon, where Q is selected from the group consisting of alkyl, phenyl, and substituted phenyl and n is an integer from about 1 to about 12, where R.sub.1 is selected from the group consisting of alkyl moieties containing from 1 up to about 20 carbon atoms, and aryl and alkaryl moieties containing from 7 up to about 20 carbon atoms, and where R.sub.2 is selected from the group consisting of hydrogen, alkyl moieties containing from 1 up to about 20 carbon atoms, alkylaminocarbonyl moieties having two to 10 carbon atoms, arylaminocarbonyl moieties having 6 to about 10 carbon atoms, and acyl moieties containing from 2 up to about 20 carbon atoms.
