Usage

General Description

2-Methyl-2-pentanethiol is a chemical compound with a formula of C6H14S. It is a colorless liquid with a strong, unpleasant odor. This chemical is commonly used as a flavoring agent in food products, particularly in the production of meat and dairy flavors. It is also used in the production of perfumes and fragrances, as well as in the manufacture of rubber and plastics. 2-Methyl-2-pentanethiol is highly flammable and can cause irritation to the skin, eyes, and respiratory system if exposed to it in high concentrations. Due to its strong odor, it is often added to natural gas to give it a distinct smell for safety purposes.

Organic preparations with molar amounts of volatile malodorous thiols

Thiols are indispensable for the preparation of many organic sulfur compounds. Their strong smell and use for gas leakage perception render it almost impossible to work with them without arousing public attention. Molar amounts of the very odoriferous thiol 2-methyl-2-propanethiol (t-butylthiol) are needed, for example, for the large-scale synthesis of two useful synthetic building blocks, 1,2,4,5-tetrakis(t-butylthio)benzene and tetramethylbenzo-2,2, 6,6-[1,2-d;4,5-d']bis[1,3]dithiol. We investigated an array of alternatives to circumvent the problem: (1) alternative thiols (primary, long-chain, tertiary thiols of larger molar mass); (2) exhaust cleaning methods (adsorption, oxidation, conversion to a salt); and (3) thermal exhaust treatment. Only combustion of the fumehood exhaust with domestic gas at 900 °C in a regenerative thermal oxidation unit was able to completely prevent the thiol smell from escaping.
