  應用:工業噻吩中微量水分測定 氣相色譜法

噻吩（Thiophene），系統名1-硫雜-2,4-環戊二烯，CAS號110-02-1。從結構式上看，噻吩是一種雜環化合物，也是一種硫醚。分子式C4H4S，分子量84.14。熔點-38℃，沸點84℃，密度1.051g/cm3。在常溫下，噻吩是一種無色、有惡臭、能催淚的液體。噻吩天然存在于石油中，含量可高達數個百分點。工業上，用于乙基醇類的變性。和呋喃一樣，噻吩是芳香性的。硫原子2對孤電子中的一對與2個雙鍵共軛，形成離域Π鍵。噻吩的芳香性僅略弱于苯。
噻吩中水分含量是工業用噻吩需要控制的重要一項指標，國標中規格:標準中規定:水分質量百分比:優等品≤0.06%；合格品≤0.09%

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.
