Abstract:The porous polymer beads of styrene divinylbenzene copolymer (GDX203) were nitrated by different proportion of HNO\-3(65%)\|H\-2SO\-4(98%) mixture at room temperature.The nitrogen content and nitro\|group were confirmed with elementary analysis and IR spectrum.The modified GDX203 was used as chromatographic stationary phase for analysis of carbonylation products of methanol.The optimum gas chromatographic stationary phase was selected from modified GDX203 of different nitrogenous contents.The results showed that by using a modified column of proper nitrogen content all components in the reaction medium were separated at constant chromatographic temperature,especially CH\-3COOCH\-3 and CH\-3I can be separated completely.The gas chromatographic analysis of five components was accomplished in 6 minutes.
Keywords:GDX203  Nitration  Gas chromatographic stationary phase    Methanol  carbonylation
