What is tertiary dodecyl mercaptan?
Tertiary dodecyl mercaptan (TDM) is commonly used as a chain transfer agent in the manufacturing process of styrene/butadiene latex for use in carpet and paper industries.
What 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.
How are Thiolates formed?
Sodium thiolates have also been formed by the action of sodium metal on a thiol in ethanol. The high yields of the subsequent reactions demonstrate the near quantitative yield of the intermediate sodium thiolates <63JOC593, 70JCS(C)2409, 77S795>.
What is the chemical mercaptan used in?
It is used as a gas odorant; an intermediate in the production of pesticides, jet fuels, and plastics; and in the synthesis of the amino acid methionine. Because methyl mercaptan is a gas a ambient temperature, the most likely exposure routes are inhalation and dermal.
Which chemical is used in phenyl?
One of the basic chemicals that contain phenyl is phenol (C6H5OH).
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.
What is mercaptan chemistry?
Mercaptans, commonly referred to as thiols, are organosulfur molecules composed of carbon, hydrogen, and sulfur that are known for having a pungent odor similar to rotten cabbage or garlic. In nature, these compounds can be found in living organisms as a waste product of metabolism, and also in oil and gas.
Where is mercaptan found?
Mercaptans are most commonly found in as an emission from paper or pulp mills, and in coal tar and petroleum distillates. Sometimes, mercaptans can be found naturally in food, including onions, asparagus, and radishes.
How is mercaptan produced?
4.1 PRODUCTION Methyl mercaptan is produced commercially by the reaction of hydrogen sulfide with methanol (Santodonato et al. 1985; Windholz 1983). Methyl mercaptan is manufactured by the Organic Chemical Division of Pennwalt Corporation in Beaumont and Houston, Texas.
Where is mercaptan made?
OVERVIEW. Methyl mercaptan (METH-uhl mer-KAP-tan) is a colorless, highly flammable, foul-smelling gas with the odor of rotten cabbage released from decaying animal and vegetable matter. It is also produced in the intestinal tract by the action of bacteria on a variety of proteins known as the albumins.
