| Abstract: | The gas chromatographic analysis of the main product and by - product of production of diketene by cracking of acetic acid was studied. Under the conditions with the column of SE-30, detector of TCD, column temperature of 120 -200 ℃ , heating rate of 5 ℃ / min, by the internal standard, the correlation coefficients R2 was 0.9918 for diketene, 0. 9997 for acetic anhydride, 0. 9907 for acetic acid, 0.9823 for acetone. This method is simple, rapid, reproducible, and adapted to diketene quantitative Analysis. |
