Furfural in furfuryl alcohol gross production was determinated by GC of packed-column made up of β-cyclodextrain derivative. Furfuryl alcohol and furfural were well separated,the relative retention and resolution were respectively 1.75 and 4.35.The linear relation coefficient of standard curve was 0.999 94.The mean standard deviation of pure furfural was 0.052%(n=5).The coefficient of variation of furfural samples was 1.84%(n=5). The mean recoveries of two samples standard addition test were respectively 97...
