工业上，噻吩用丁烷与硫作用制取，丁烷先脱氢，然后再与硫关环，形成噻吩。实验室中，噻吩用 1,4-二羰基化合物与三硫化二磷反应制取。乙酰基丁酮与硫化磷反应，能生成2,5-二甲基噻吩。
滕州市浩瀚色谱仪器技术服务有限公司，采用《工业用噻吩测定毛细管柱》，噻吩及杂质得到有效分离，结果满意。




Industrial thiophene determination capillary column
Industrial thiophene determination capillary column Details:

Stationary phase: 7% cyanopropyl-7% phenyl-86% methylpolysiloxane
Specification: 30m*0.25mm*0.5um
Model: HH-1701
Application: HG/T 4793-2014 Industrial thiophene

Industrially, thiophene is prepared by the action of butane and sulfur. Butane is first dehydrogenated and then closed with sulfur to form thiophene. In the laboratory, thiophene is prepared by reacting a 1,4-dicarbonyl compound with phosphorus disulfide. Acetyl butanone reacts with phosphorus sulfide to form 2,5-dimethylthiophene.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. adopted "Chemical Thiophene Determination Capillary Column", and thiophene and impurities were effectively separated, and the results were satisfactory.
