| 摘 要： | 采用紫外光谱法测定乙酸乙烯酯中对苯二酚含量时,乙酸乙烯酯中的有机杂质会对测试结果产生影响.其中乙醛、丙酮对测试结果的影响程度基本呈线性递增关系,而醋酸甲酯、醋酸乙酯对测试结果不会产生影响.

| Abstract: | When UV spectrophotometry was used to determine the content of hydroquinone in vinyl acetate, the organic impurities contained in vinyl acetate will affect the test results. The effects of acetaldehyde and acetone on the test results linearly increase with increasing the amounts of acetaldehyde and acetone. Whereas, the methyl acetate and ethyl acetate do not af- fect the test results. |
