Ethereal-sweet

Observable Characteristics - Physical State (as normally shipped) Liquid Color Colorless Odor Sweet ethereal. 

Colorless to faint-yellow mobile liquid with a sweet, ethereal odor. On standing, the odor becomes a foul stench. This material is hazardous through inhalation, skin absorption of the liquid, and ingestion, and produces local skin/eye impacts.

Clear, colorless, volatile, flammable liquid with a penetrating, sweet, ether-like odor. Experimentally determined detection and recognition odor threshold concentrations were 70 pg/m (17 ppbv) and 220 pg/m (53 ppbv), respectively (Heilman and Small, 1974). 

Colorless, liquefied compressed gas, with a sweet, ethereal odor. Volatile flammable gas. An experimentally determined odor threshold concentration of >100 ppmy was reported by Leonardos et al. (1969). 

Description Colourless transparent liquid, with a sweet ethereal odour (American Conference of Governmental Industrial Hygienists, 1992 Budavari, 1996)... 

Note Highly polar solvent sweet, ethereal odor soluble in water flammable, burns with a luminous flame highly toxic by ingestion, inhalation and skin absorption miscible with water, methanol, methyl acetate, ethyl acetate, acetone, ethers, acetamide solutions, chloroform, carbon tetrachloride, ethylene chloride, and many unsaturated hydrocarbons immiscible with many saturated hydrocarbons (petroleum fractions) dissolves some inorganic salts such as silver nitrate, lithium nitrate, magnesium bromide incompatible with strong oxidants hydrolyzes in the presence of aqueous bases and strong aqueous acids. Synonyms methyl cyanide, acetic acid nitrile, cyanomethane, ethylnitrile.

D 0.92 (20C), bp -23.7C, fp -97.6C, flash p approximately 32F (0C), refr index 1.3712 (—23.7C), critical temperature 143C, critical pressure 970 psi absolute, autoign temp 1170F (632C), bulk d 7.68 lb/gal (20C). Slightly soluble in water, by which it is decomposed soluble in alcohol, chloroform, benzene, carbon tetrachloride, glacial acetic acid attacks aluminum, magnesium, and zinc.

Colourless volatile liquid sweet ether-like odour. Can be absorbed through skin as well as by inhalation. Slowly metabolized to cyanide. Clinical effects delayed. >850 mg/m3 weakness, nausea, convulsions, death. 

The odor is very sharp and pungent, rather irritating and penetrating, becoming sweet-ethereal, not unpleasant in extreme dilution (Arctander, 1967). 

It is a mobile, narcotic, flammable liquid whose over-exposure irritates eyes and upper respiratory system (Merck Index). It has a sweet-ethereal, fruity taste in water (Arctander, 1967). An odor threshold of 17 ppm in water was given by Mulders (1973b). 

Isopropyl formate has a sweet-ethereal, very diffusive odor, fresher than chloroform, not as pungent as propyl formate (Arctander, 1967). 

This ester has a very diffusive and penetrating, sweet-ethereal, fruity odor. In extreme dilution it is reminiscent of apple peel with a slightly fatty peach-like undertone (Arctander, 1967). It has a fruity, over-ripe, cheesy flavor (Chemisis, 1999). The probable threshold would be 43 ppb in water (confidence limits 15-120 ppb) according to Ahmed et al. (1978) and the probable flavor threshold 59 ppb (confidence limits 23-150). 

Powerful and diffusive, sweet-ethereal, burnt odor, in extreme dilution rather pleasant, warm and sweet (Arctander, 1967). The flavor is described as alliaceous, dirty, musty, phenolic and medicinal (Chemisis, 1998). An odor threshold of 8.0 ppm in cottonseed oil is given by Evans et al. (1971). 

Trichloroethane is a volatile, colorless liquid and its vapor is heavier than air. It has a sweet, ethereal odor. It is poorly soluble in water but dissolves in other solvents, such as acetone, benzene, ethanol, and carbon tetrachloride. The vapors of I, I, I-trichloroethane are heavier than air and may travel a considerable distance from the evaporation source. In contact with water or humidity, trichloroethane decomposes slowly yielding corrosive acids. In normal working conditions... 

PHYSICAL PROPERTIES colorless gas at room temperature sweet, ether-like odor liquid below 12°C miscible in water and alcohol very soluble in ether MP (-112°C, -... 

Water-clear, highly refractive, mobile liquid with an agreeable, sweet, ether odor poisonous stable to air and water. B.p. 76°C, df 1.291. Insoluble in water miscible in all proportions with ether, absolute alcohol and other organic solvents. 

Colorless, highly refractive, mobile liquid with an agreeable, sweet, ether odor poisonous stable to air and water quite flammable. 

Physical Description Colorless to faint-yellow liquid with a sweet ether-like odor. [Note Reagent grades are foul smelling.] ... 

Coloriessliquid. Sweet, ether-like or chlorolorm-like odor occurs below Ihe TLV and Is a good warning property. Polymerizes readily.
