摘　　要：开发研究了氯乙酸副产盐酸的精制工艺及盐酸中有机杂质的紫外分光光度分析方法。副产盐酸经酸洗、吸收、蒸馏得高纯盐酸。中试结果表明 ,工艺合理 ,精制盐酸达到GB 32 0 -The refining technology of hydrochloric acid by product from producing chloroacetic acid is developed and studied. The method for analyzing organic impurities by ultraviolet absorption spectra is determined. The high purity hydrochloric acid is produced by acid washing, absorbing and evaporating. The results of pilot test show that the technology is reasonable, and the quality of refined hydrochloric acid reaches the standard of GB320-93.
