Tetrahydrophene, also known as thiophene or THT for short, is widely used in Europe and its affiliated regions and gradually extended to major developed enterprises around the world. Its taste is considered to be closest to the gradually replaced gas taste. In terms of chemistry, tetrahydrothiophene is the most stable compound used for gas odorization. Compared with other odorants, tetrahydrothiophene has the advantages of strong antioxidant performance, stable chemical properties, long odor retention time, no residue after burning, no environmental pollution, low addition amount, and low corrosiveness. It is usually used in its pure undiluted form.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established an analytical method for tetrahydrothiophene in natural gas using gas chromatography. The method uses a HH-THT-7 specialized micro diameter packed chromatography column and TCD detector for detection, and a tetrahydrothiophene working curve is plotted. The low detection limit of tetrahydrothiophene can reach 0.5mg · m-3. After 6 repeated measurements, the relative standard deviation is less than 0.02%. This method has been used for the determination of tetrahydrothiophene in natural gas and has achieved satisfactory results.

四氫噻吩又叫噻吩烷或簡(jiǎn)稱THT，主要在歐洲及歐洲附屬的區(qū)域中廣泛應(yīng)用并逐漸延伸到世界主要發(fā)達(dá)企業(yè)，它的味道被認(rèn)為最接近于被逐漸取代的煤氣味道。就化學(xué)而言，四氫噻吩是用于氣體加臭最穩(wěn)定的化合物。四氫噻吩與其它加臭劑相比，具有抗氧化性能強(qiáng)、化學(xué)性質(zhì)穩(wěn)定、氣味存留時(shí)間久、燒后無殘留物、不污染環(huán)境、添加量少、腐蝕性小等優(yōu)點(diǎn)。它通常以純的未稀釋形式使用。
