[0002] Thiophene, whose chemical name is 1-thia-2,4-cyclopentadiene, is a heterocyclic compound and also a sulfide with the molecular formula C4H4S. At room temperature, thiophene is a colorless, foul-smelling, tear-inducing liquid. Thiophene exists naturally in petroleum, with a content of up to several percentage points. In industry, it is used for the denaturation of ethyl alcohols. Like furan, thiophene is aromatic.

[0003] In order to ensure the extraction purity of thiophene, thiophene is usually extracted by distillation. Similar to the traditional distillation method of other substances, during the distillation extraction of thiophene, the distilled thiophene vapor needs to be condensed through a condenser and collected. In order to ensure the condensation effect of the thiophene vapor, a longer condenser needs to be used. However, a longer condenser will take up a larger space, which brings inconvenience to the extraction of thiophene. Utility Model Content
