| Abstract: | The foramaldehyde is that the methanol is oxidized in the potassium permanganate and phosphoric acid,Under certain temperature,one kind of purple compound is that reaction comes into being from formaldehyde and the chromatrop-ic acid.Be in 570 nm places of the ultraviolet-visible pectrophotometer,the colorimetric is determined,required quan-tity of heat is provide from pule sulfuric acid.Use the way to measure the whole content of methanol in exhausted gas. |
