摘　　要：利用吸附法,考察了活性炭、离子交换树脂精制环丁烯砜的方案,利用UV-Vis,FTIR,XRD对其进行分析检测,重点对环丁烯砜、环丁砜的FTIR谱图进行了解析。活性炭、离子交换树脂串联去除工业级环丁烯砜杂质的效果最佳。利用精制的环丁烯砜催化加氢,合成出了高纯度的环丁砜,转化率大于99.8%,为工业装置技术改造提供了实验依据。Purification of raw sulfolene was investigated by adsorption method using activated carbon and exchange resin, and the sulfolene was detected by UV-Vis, FTIR and XRD. FTIR spectra of sulfolene and stdfolane were especially analyzed. The results showed that it was the best way to purify industrial grade sulfolene by activated carbon connected exchange resin. The sulfolane with high quality was synthesized by purified sulfolene through catalytic hydrogenation with catalyst. The conversion efficiency was more than 99.8%. It could provide experimental data for the technical reform of industry equipment.
