| Abstract: | The determination method of formaldehyde,water,2-methyl-pyritine,acetic acid and 2-hydroxyethyl-pyritine in the solution of synthesizing 2-hydroxyethyl-pyritine by GC was discussed.The relative retention was used as qualitative analysis,and the quantitative analysis was corrected area normalization method.The results show that the methods is simple,rapid and with good reproducibility.It can be used for the control analysis of synthesizing 2-hydroxyethyl-pyritine with satisfactory results.Relative deviation of the method is smaller than 3%. |
