What is tetrahydrothiophene used for?
Tetrahydrothiophene is a colorless liquid with an unpleasant odor. It is used as a solvent, chemical intermediate, fuel gas odorant, insecticide, and bird and moth repellent.
Is tetrahydrothiophene a good Nucleophile?
Indeed, reinvestigation of the NMR spectra recorded during the poly- merization shows the presence of tetrahydrothiophene, a rela- tively strong nucleophile, in the reaction mixture aer only 2 h of reaction (Fig.
Is tetra hydro thiophene aromatic?
Tetrahydrothiophene is a heterocyclic organic compound consisting of a five-membered ring containing four carbon atoms and a sulfur atom. It is the saturated analog of thiophene. It is a volatile, clear, colorless liquid with a strong unpleasant odor….
|Boiling point||119 °C|
Is c4h8s organic?
Belongs to the class of organic compounds known as thiolanes. These are organic compounds containing thiolane, a five-member saturated ring containing four carbon atoms and a sulfur atom….Structure for FDB029635 (tetrahydrothiophene)
How do you make Tetrahydrothiophene?
Tetrahydrothiophene is prepared by the reaction of tetrahydrofuran with hydrogen sulfide. This vapor-phase reaction is catalyzed by alumina and other heterogenous acid catalysts. This compound is a ligand in coordination chemistry, an example being the complex chloro(tetrahydrothiophene)gold(I).
What does Tetrahydrothiophene smell like?
The odorant which Gasunie adds is called tetrahydrothiophene (THT). The concentration of THT in the gas is 18 mg/m3. THT is a colourless liquid which smells of rotting eggs. The low detection threshold of this substance is especially vital.
Is naphthalene in cigarette smoke?
Naphthalene is made from crude oil or coal tar. It is also produced when things burn, so naphthalene is found in cigarette smoke, car exhaust, and smoke from forest fires. It is used as an insecticide and pest repellent.
What is tetrahydrothiophene made of?
Tetrahydrothiophene is a five-membered, fully saturated, sulfur heterocycle comprised of four sp 3-hybridized carbon atoms and a sulfur atom. It is also known as thiolane or thiophane.
What is the standard state of tetrahydrothiophene?
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).?) Tetrahydrothiophene is an organosulfur compound with the formula (CH 2) 4 S. It contains a five-membered ring consisting of four carbon atoms and a sulfur atom. It is the saturated analog of thiophene.
What is tetrahydrothiophene used for in LPG?
Because of its smell, tetrahydrothiophene has been used as an odorant in LPG, albeit no longer in North America. It is also used as an odorant for natural gas, usually in mixtures containing tert-butylthiol . Tetrahydrothiophene is a Lewis base classified as a soft base and its donor properties are discussed in the ECW model .
What are chiral tetrahydrothiophenes (thts)?
A convenient preparation of chiral tetrahydrothiophenes (THTs) in high enantiopurity via phosphorothioic acids circumvents the use of H 2 S which is a highly toxic gas. The key transformation is a base-promoted, intramolecular, highly stereospecific carbon-sulfur bond-forming event through a double S N 2 displacement mechanism.
