| 摘 要： | 研究了气相色谱法分析氯乙酸样品时酸化过程对分析结果的影响，研究表明，采用阳离子交换树脂作酯化反应催化剂，无水硫酸镁作脱水剂，氯乙酸样品和过量甲在368K下能快速酯化，酯化后的样品仅需简单过滤便可进行色谱分析，该方法操作简便，数据可靠，能快速测定氯乙酸样品，可用于氯乙酸生产的中控分析。 |

| Abstract: | The effect for esterification on analysis of the chloroacetic acid is studied. The sample of chloroacetic acid product is esterified to relative acetates under the suitable conditions of cation exchange resin, dehydration regent of Magnesium sulfate and excessive methanol at 373K. The esterified and filtered sample is determined with a gas chromatography accurately and rapidly. The method is reliable for practical production. |
| Keywords: | chloroacetic acid gas chromatography esterification analysis |
