What are the uses of thiols?
Thiols are used as odorants to assist in the detection of natural gas (which in pure form is odorless), and the “smell of natural gas” is due to the smell of the thiol used as the odorant….CHEBI:29256 – thiol.

How is thiophenol made?
Thiophenol can be manufactured from chlorobenzene and hydrogen sulfide over alumina at 700 to 1,300 °F (371 to 704 °C). The disulfide is the primary byproduct. The reaction medium is corrosive and requires ceramic or similar reactor lining. Aryl iodides and sulfur in certain conditions may also produce thiophenols.
Why do mercaptans smell?
Mercaptans bond strongly with mercury compounds, and most release strong odours that resemble garlic or rotting cabbage. These compounds are detectable by the human nose at concentrations as small as only 10 parts per billion, making them an effective odourant.
What does mercaptan smell like?
rotten eggs
Mercaptan is an additive in natural gas that produces an odor similar to rotten eggs or cabbage. If you smell this odor in the home, you could have a natural gas leak.
What are thiols in food?
A Thiol is a sulfur compound which occur in many foods including garlic, onion, cabbage, coffee, chocolate, beans, chlorella and coriander leaf. All are foods that we’re encouraged to consume as part of a healing diet.
Where are thiols found?
Thiols are found in nature mainly in more complex combinations. Cysteine, for example is a common amino acid having an SH group. Volatile thiols are known for their strong odor. As an example, 1-butanethiol has an odor threshold of 6 ppb in water and a flavor threshold of 0.004 ppb.
What is C6H5SH?
Benzenethiol | C6H5SH – PubChem.
Why is thiophenol more acidic than phenol?
Thiophenol has appreciably greater acidity than does phenol. Thiophenol has a pKa of 6 vs 10 for phenol. This is because the lone pair of sulphur is more easily given to ring(than in phenol) and stabilised after losing the H+. Since the conjugate base is more stable the acid is more acidic.
