  Application: Determination of trace moisture in industrial thiophene by gas chromatography

Thiophene, system name 1-thia-2,4-cyclopentadiene, CAS number 110-02-1. From the structural formula, thiophene is a heterocyclic compound and a thioether. Molecular formula C4H4S, molecular weight 84.14. Melting point -38℃, boiling point 84℃, density 1.051g/cm3. At room temperature, thiophene is a colorless, foul-smelling liquid that can cause tears. Thiophene exists naturally in petroleum, and its content can be as high as several percentage points. In industry, it is used for denaturation of ethyl alcohols. Like furan, thiophene is aromatic. One of the two lone electrons of the sulfur atom is conjugated with two double bonds to form a delocalized Π bond. The aromaticity of thiophene is only slightly weaker than benzene.
The moisture content in thiophene is an important indicator that needs to be controlled for industrial thiophene. The national standard specifies: the standard stipulates: moisture quality percentage: excellent product ≤0.06%; qualified product ≤0.09%

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd., advancing with the times, exclusively developed a special capillary column for the determination of trace thiophene in industrial thiophene, with high column efficiency, good separation, and satisfactory results. Haohan Chromatography, a leader in Chinese analytical technology.
