| Abstract: | A method for determining monoprotic organic acids content in cyclohexane oxidation liquid by gas chromatography was established using GC-2010 gas chromatograph,thermal conductivity detector,FFAP 50 m×0.32 mm×0.4μm chromatographic column by temperature programming and external standard quantification.The results showed that the method accurately determined the contents of foric acid,acetic acid,propionic acid,butyrate,valeric acid and hexanoic acid in oxidation liquid. The linear correlation coefficients of these six monoprotic organic acids were all higher than 0.98,the relative standard deviation 2.38%-5.70%,and the recovery rate 93.9%- 101.0%. |
