摘要
环己烷作为一种重要的有机试剂,在工业生产、实验室分析等领域有着广泛的应用。利用环己烷的熔点与其杂质差异较大的特点,通过重结晶-过滤提纯-萃取除醇-干燥脱水等步骤,获得了纯度为99.998%的高纯环己烷,各项指标优于T/CRIAC 0072—2022《化学试剂高效液相色谱用试剂环己烷》中相关指标要求。解决了环己烷试剂痕量杂质除去难度大、成本高等问题。降低了环己烷的提纯成本,减少了环境污染。所获得的高纯试剂环己烷在光谱分析、痕量污染物分析、化工合成等领域有着广泛的应用前景。
As an important organic reagent,cyclohexane has been widely used in industrial production and laboratory analysis.In this work,a recrystallization-filtration purification-extraction alcohol removal-drying and dehydration method was adopted to obtain 99.998%cyclohexane based on the distinct melting points between cyclohexane and other impurities.The indicators are better than the relevant requirements in T/CRIAC 0072—2022“Chemical reagent cyclohexane for high-performance liquid chromatography”.It solves the problems of difficulty and high cost of removing trace impurities of cyclohexane reagent.It reduces the purification cost of cyclohexane and reduces environmental pollution.The obtained high-purity cyclohexane has broad application prospects in spectral analysis,trace contaminant analysis,chemical synthesis,and other fields.
