Abstract

Poly(p-tert-butyltrimethoxymonopropyloxycalix [4]arene-methylsiloxane) (TBCX-MS) has been prepared and used as a stationary phase in isothermal capillary gas chromatographic separation of some positional isomers. Retention factors (k) and separation factors (a) for the isomers were measured and compared with those on poly(p-tert-butyl-dimethoxydiprspyloxycalix[4]arene-tetramethyldisiloxane) (TBCX-TMDS), poly(dimethoxy-dipropyloxycalix [4]arenetetramethyl-disiloxane) (CX-TMDS). Most of the isomers investigated are well resolved on TBCX-MS. Retention of all the compounds decreases on the three phases in the order, TBCX-TMDS greater than or equal to TBCX-MS > CX-TMDS. Similar retention values on TBCX-TMDS and TBCX-MS seem to indicate that retention property of the two phases is not significantly affected by the spatial position of the calixarene moiety.
