Description

Product Detail

Ethyl mercaptan is an important pesticide intermediate, which is used for the production of organophosphorus pesticides such as isopropyl phosphate, phorate, phorate, internally absorbed phosphorus, methyl internally absorbed phosphorus, etc. It can also be used to produce antibacterial agent 401. When the concentration of ethanethiol in the air is only 1/50 billion, its odor can be detected, so it can be used as a warning agent for natural gas and petroleum gas, as well as a odorant for reagents (its odor can be detected when the concentration is 0.00019mg/L). Ethyl mercaptan can also be used in organic synthesis such as medicine.

Physical Properties:

Colorless liquid with a strong, disagreeable, skunk-like or rotten egg odor. Extremely flammable liquid or gas. An experimentally determined odor threshold concentration of 1 ppbvwas reported by Leonardos et al. (1969). Katz and Talbert (1930) reported experimental detection odor threshold concentrations in the range 0.66–7.6 μg/m3(0.26 to 3.0 ppbv).

Appearance:

Ethyl mercaptan appears as a clear colorless low-boiling liquid (boiling point 97°F) with an overpowering, garlic-like/skunk-like odor. Flash point -55°F. Less dense than water and very slightly soluble in water. Vapors are heavier than air. Vapors may irritate nose and throat. May be toxic if swallowed, by inhalation or by contact. Added to natural gas as an odorant. Used as a stabilizer for adhesives.
