Tetrahydrothiophene (referred to as thiophene), also known as thiophene heterocyclic pentane, tetramethylene sulfide, butyl sulfide, tetrahydrothiophene, is thiophene after catalytic hydrogenation to get a sulfur saturated heterocyclic compound, thiophene was reduced to tetrahydrothiophene, no longer has a conjugated system and aromatic, so tetrahydrothiophene shows the nature of general sulfur ether, easy to oxidize to sulfoxide and sulfone (sulfoxide). Thiophene is colorless transparent volatile liquid, insoluble in water, can be miscible in ethanol, ether, benzene, acetone. Has a strong unpleasant odor, it produces a stable odor, not easy to distribute, the presence of 0.01PPm in the air can smell, gas equipment Chemicalbook, transportation pipeline gaskets and other materials are not corrosive, the human smell will not produce habit passivation, so used as urban gas, natural gas and other gas fuel leakage warning agent, It is added to the gas fuel in a small amount, eliminating the original use of ethyl mercaptan and other odor enhancers. At present, the domestic market needs about 400 tons of thiophene/year, mainly relying on imports. Thiophene has an anesthetic effect. When the mice were poisoned by inhalation, motor excitement, ataxia, anesthesia, and finally death occurred. In chronic poisoning experiments, mice showed abnormal behavior, halting weight gain and changes in liver function. In addition, it is also used as medicine, pesticides and organic synthesis raw materials.
It is used as odorant for fuel gases such as city gas, petroleum liquefied gas and natural liquefied gas, and can also be used as raw materials for medicine and pesticides
Sinezimboni eziningi zekhwalithi ephezulu ngokubambisana okujulile, ezingakunikeza ngemikhiqizo yekhwalithi ephezulu namanani ancintisanayo. Futhi singanikeza izaphulelo zokuthenga ngobuningi.Futhi sibambisana nezinkampani eziningi ezichwepheshile zokudlulisa impahla, zingaletha imikhiqizo ngokuphepha nangokushelela ezandleni zakho.
