Wholesale THT tetrahydrothiophene 99.5% barreled and canned for North China gas odorizing liquid

Under the current national policy of converting coal to gas and the large-scale entry of natural gas into households, the gas odorizer tetrahydrothiophene plays a crucial role, such as how to detect natural gas leaks, natural gas pressure reduction testing, gas pipeline leak detection, etc. We should also learn about the application of this product and the prevention of natural gas leaks.

Tetrahydrothiophene is mainly used as an odorant or warning agent for urban gas, natural gas, and other gaseous fuels.

Requirements for odorants

(1) Under low concentration conditions, it can smell odors and distinguish odors from other odors.

(2) Harmless to the human body, low toxicity, and long-lasting odor retention;

(3) Stable chemical properties, non corrosive gas state, easy to store and transport;

(4) Able to burn completely, with no odor after combustion and minimal residual pollutants;

(5) After gasification, it does not condense at room temperature and is not easily adsorbed on gas transmission facilities (such as pipelines, gas meters, valves, etc.).

Tetrahydrothiophene is mainly used as an odorant or warning agent for urban gas, natural gas, and other gaseous fuels. It can also be used as raw materials for the production of pharmaceuticals, pesticides, and photochemicals. At present, according to international standards, odorants for urban gas, natural gas, and other gases must use tetrahydrothiophene, and the previously used odorants such as ethanethiol have been abolished. At present, the domestic market requires about 400 tons/year of tetrahydrothiophene, mainly relying on imports. It is expected that the market demand will reach over 1600 tons/year by the end of the "Tenth Five Year Plan".

Tetrahydrothiophene THT is the main natural gas odorant used internationally.

Definition of tetrahydrothiophene: An organic compound or mixture with a strong odor. When added to gas at a very low concentration, the gas has a special and unpleasant warning odor, so that the leaked gas is detected when it reaches its lower explosive limit of 5% or reaches the allowable harmful concentration to the human body.

Tetrahydrothiophene, also known as THT, with CAS registration number 110-01-0, is mainly used as an odorant or warning agent for urban gas, natural gas, and other gaseous fuels. It can also be used as raw materials for the production of pharmaceuticals, pesticides, and photochemicals.
