摘　　要：用紫外分光光度法检测盐酸中的微量乙酸。确定了乙酸的最大吸光度和相关线性范围。检测了不同浓度的乙酸在 10 % (体积分数 )盐酸中的线性关系。认为在 10 %盐酸中 3 8g·L- 1的乙酸呈良好的线性关系。该方法简便、实用、快速。适用于氯乙酸合成生产线的盐酸检测。The acetic acid content is determined by the UV spectrophotometric method in hydrochloric acid which is obtained as a by product in the production of chloroacetic acid. The optimum condition for the determination is studied and a good linearity between the absorbance and concentration of acetic acid at 203nm is found in the range of 3~8g·L -1 in sample solutions of 1+9 HCl. This method is convenient, practical and rapid.
