主　　题：modification GDX stationary phase synthesis of methyl acrylate FT-IR 

摘      要：This paper describes a GDX stationary phase modified by coating and oxidizing for gas chromatographic analysis of alcohols. ketones,acids, esters and amines. The selectivities and the resolutions for methyl acrylate and methyl propionate were improved on the modified GDX. After the modification, the column length was shortened from 3 to 2 m and the analysis time was reduced from 30 to 10 min. The relative standard deviations are less than 5% and the recoveries are in the range of 97～103%.
