| Abstract: | The analysis method of the ethyl 2,3-dicyanopropionate was established with the gas chromatography（GC） in this paper.Dimethyl（o-） phthalate was selected as internal standard substance,and the quantitative method was internal standard curve method,the correlation coefficient r was 0.9992,the accuracy of the method as RSD was 0.34%,and the average recovery was 98.13%～101.65%.This method is found to be sensitive,simple,accurate and reproducible,and it can be used for the determination of 2,3-dicyanopropionate in production. |
