| Abstract: | Acetic acid in air is collected in absorption solution of Na 2CO 3.With the existence of concentrated sulfuric acid,acetate and methanol derive into methyl acetate.The derived product methyl acetate is separated by wide-pore capillary column AT-WAX (30m *0.53um *1.2um) and then determined by gas chromatography. |

| Keywords: | air acetic acid derivatization capillary column gas chromatography |
