What do they add to natural gas to make it smell?
mercaptan
For easy detection, we add a harmless chemical called mercaptan to give gas a distinctive odor. Most people describe the smell as rotten eggs or hydrogen sulfide like odor. It smells bad for a good reason – in case of a gas leak!
What foods produce methanethiol?
It has been isolated from higher plants, such as radish (Raphanus sativus). It is also present in orange juice, pineapple, strawberries, asparagus, wheat bread, gruyere cheese, hop oil, coffee, roasted filberts, cooked rice and other foods.
What is mercaptan made from?
Mercaptan is a non-toxic substance that is made of carbon, hydrogen, and sulfur. Because it’s regularly found in nature as a waste product for both animals and humans, mercaptans are also organic and extremely foul-smelling. That being said, mercaptans provide a number of advantages for industrial purposes.
Is mercaptan in natural gas?
Mercaptan is also known as methanethiol and is a harmless but pungent-smelling gas which has been described as having the stench of rotting cabbages or smelly socks. It is often added to natural gas, which is colorless and odorless, to make it easier to detect.
Is methanethiol toxic?
Methyl mercaptan (CASRN 74-93-1; CH4S), also known as methanethiol, is a toxic, extremely flammable, colorless gas with a smell similar to rotten cabbage. It occurs naturally in the blood and brain, and in other animals and plant tissues. It is one of the main chemicals that cause bad breath and the odor of flatulence.
Which chemical is used in LPG for smell?

Our noses tend to adjust to this smell quickly, so even if it disappears, there still could be a sewage problem.
What is the structure of methanethiol?
CH4SMethanethiol / Formula
What functional group is methanethiol?
thiol functional group
Methanethiol, also known as methylmercaptan, belongs to the class of organic compounds known as alkylthiols. These are organic compounds containing the thiol functional group linked to an alkyl chain. Methanethiol exists in all living species, ranging from bacteria to plants to humans.
