tert-Butylthiol is the main ingredient in many gas odorant blends. It is always utilized as a blend of other compounds, typically dimethyl sulfide, methyl ethyl sulfide, tetrahydrothiophene or other mercaptans such as isopropyl mercaptan, sec-butyl mercaptan and/or n-butyl mercaptan, due to its rather high melting point of − °C ( °F Abbreviations: TBM.

BUTYL MERCAPTAN is incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents.

Reactions with these materials generate heat and in many cases hydrogen gas. May liberate hydrogen sulfide upon decomposition or reaction with an acid.

Context: Ina lightning strike caused a leak of tert-butyl mercaptan from its storage tank at the Gulf South Natural Gas Pumping Station in Prichard, Alabama.

On Jthe Alabama Department of Public Health requested Centers for Disease Control and Prevention epidemiologic assistance investigating possible health effects resulting from airborne exposure. Methyl mercaptan, or methanethiol, is a colorless, flammable gas with a distinct odor that smells like rotten eggs or cabbage.

It is found in coal tar and petroleum distillates and as an emission from paper and pulp mills. Methyl mercaptan occurs naturally in some foods (e.g., onions, radishes, asparagus, some nuts and cheese). The two scent glands are located on opposite sides of the anus with each having a short tube that extends out slightly on each side of the anus when the yellowish colored butyl mercaptan containing liquid is sprayed.

Human Metabolome Database (HMDB) Butyl mercaptan appears as a clear, colorless liquid with a strong skunk-like odor. Detection limit samples were generated from a dry atmosphere containing approximately mg/m 3 methyl mercaptan by sampling for 5 min at approximately L/min.

The amount of methyl mercaptan recovered was near the analytical detection limit ( µg per sample) for a sample extracted into mL of methylene chloride. Full text of "Biochemical studies of mercaptan." Normal butyl-mercaptan is found in the anal secretion of all the members of the skunk family together with butyl sulfide and traces of methyl-mercaptan.^ In a report of his travels in northern Texas, Loew says'^: "I had an opportunity of studying the excretion of Mephitis Texana, but the.
