[Purification of sulfolene and its UV-Vis and FTIR spectral analysis].
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 sulfolane 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.
