説明
Respective determination of acetaldehyde and acetone is often necessary in vinyl acetate industry. When acetaldehyde in vinyl acetate is determined by hydroxylamine HCl method without modification, it is thought that acetone in the sample also reacts on hydroxylamine partially or fully. The author has found that the obtained value of acetaldehyde includes total acetone, indicating that it reacts on hydroxylamine completely. From this reason, measurements of ultraviolet spectra through a 10 mm layer of vinyl acetate were proposed by the author. By the estimation of light absorbancy at 290 mμ and 300 mμ, less than 0.05% of acetaldehyde and acetone can be determined simultaneously and respectively with an accuracy of ±0.002%, the limit of detection being 0.002% for both. As compared with the other methods of instrumental analysis, the proposed one is thought to be the most useful for the routine works.
