溶解度：6.8g/l

酸度系數(shù)(pKa)：10.6(at 25℃)

形態(tài)：Liquid

顏色：Colorless

氣味 (Odor)：Ethanethiol has a strongly disagreeable odor that humans can detect in minute concentrations. The threshold for human detection is as low as one part in 2.8 billion parts of air. Its odor resembles that of leeks, onions or cooked cabbage, but is quite distinct. Ethanethiol is intentionally added to butane and propane (see： LPG) to impart an easily noticed smell to these normally odorless fuels that pose the threat of fire, explosion, and asphyxiation.

氣味 (Odor)：Strong chunk; offensive garlic.

嗅覺閾值(Odor Threshold)：0.0000087ppm

爆炸極限值(explosive limit)：2.8-18%(V)

水溶解性：Soluble in alcohol, ether, waterMiscible with alcohol, petroleum naphtha, acetone, dilute alkali and ether. Slightly miscible with water.

Merck：14,3726

JECFA Number：1659

BRN：773638

Henry's Law Constant：3.57(x 10^-3 atm?m³/mol) at 25 °C (Przyjazny et al., 1983)

暴露限值：TLV-TWA 0.5 ppm (～1.3 mg/m³ ) (ACGIH and MSHA); ceiling 10 ppm (OSHA); IDLH 2500 ppm (NIOSH).

穩(wěn)定性：Stable. Extremely flammable - note low flash point. Incompatible with oxidizing agents, strong acids. May form explosive mixtures with air.
