Acetone has a light ethereal-nauseating and powerful odor of very poor tenacity. Irritant at high concentration, rather pleasant in dilution (Arctander, 1967). 

Castor Oil. Castor oil [8001-79-4] (qv) is the fixed oil from the seeds of Picinus communis Linne. Pale yellowish or almost colorless, it is a transparent viscid Hquid with a faint, mild odor and a bland taste followed by a slightly acrid and usually nauseating taste. Its specific gravity is between 0.945 and 0.965. Castor oil is soluble in alcohol, and miscible with anhydrous alcohol, glacial acetic acid, chloroform, and diethyl ether. It consists chiefly of the glycerides of ricinoleic acid [141 -22-0], and isoricinoleic acid [73891-08-4], found in the small intestine. The seed contains a highly... 

By far the most important sulfide is CS2, a colourless, volatile, flammable liquid (mp — 111.6°, bp 46.25°, flash point —30°, autoignition temperature 100°, explosion limits in air 1.25 50%). Impure samples have a fetid almost nauseating stench due to organic impurities but the purified liquid has a rather pleasant ethereal smell it is very poisonous and can have disastrous effects on the nervous system and brain. CSt was formerly manufactured by direct reaction of S vapour and coke in He or steel retorts at 750 1000°C but, since the early 1950s, the preferred synthesis has been the catalysed reaction between sulfur and natural gas ... 

The velocity of the hydrolysis is approximately equal to that of methyl dichloroarsine. The ethyl arsenious oxide which forms is a colourless oil, with a nauseating, garlic-like odour, but without vesicant action, which rapidly oxidises in the air to form colourless crystals. Its specific gravity is i-8o2 at 11° C., it boils at 158° C, at 10 mm. mercury pressure and is soluble in benzene, ether and acetone.

Properties Slightly yellow or colorless liquid nauseating odor burning taste. Slightly alkaline in reaction. Soluble in water, alcohol, ether, benzene, lig-roin, and fatty oils. D 0.987, fp -42.0C, bp 115.5C, flash p 68F (20C) (CC), autoign temp 900F (482C). 

Distillation.—Distillation is carried on in pot stills. The whole process must be carried out with a great deal of care. The first distillate has a nauseating odor and a raw burning taste so that it must be rectified to eliminate objectionable ethers, aldehydes and acids. It is also customary to trap off a portion of the total rectified distillate so that it may be used for blending with succeeding distillates. 

Ethereal, slightly nauseating odor, not exactly pleasant (Arctander, 1967). 

When pure, it is a clear, volatile, narcotic, flammable liquid, overexposure to which can irritate eyes, nose and throat it has a pleasant, ethereal-fruity, brandy-like odor, somewhat nauseating in high concentration (Arctander, 1967). The odor threshold given by Flath et al. (1967) was 5 ppm (probably in water), and by Mulders (1973b) 6.2 ppm in water. The flavor threshold given by Keith and Powers (1968) was 3 ppm in water and by Siek et al. (1969) 6.6 ppm. 

It is a colorless, oily liquid, has an acrid taste and a peculiar odor, at first not unpleasant, afterward nauseating and provocative of severe headache it boils at 132 (269°.6 F.) and crystallizes at —20 (4 F.) sp. gr. 0.8184 at 15 (6 F.) it nn. os with alcohol and ether, but not with water. It burns difficultly with a pale blue flame. 

Transparent viscid, pale yellow to brownish-yellow liq peculiar odor bitter, acrid, nauseating taste, d 0.930- 0.995. Acid no. 28-95. Insol in water. Sol in benzene, chloroform, ether, oils, carbon disulfide abs alcohol, petr ether, partly in 95% alcohol. Incompai. Mineral acids, magnesia, water. 

The cyanide is a colourless crystalline compound, M.pt. 113° to 114° C., has the nauseating odour of volatile aliphatic antimonials, but beyond exerting a slight irritant action on the eyes and respiratory passages, its effects are not injurious. It is insoluble in water, but readily soluble in alcohol or ether. In air it rapidly oxidises, forming dimethylstibine oxycyanide, (CH3)2SbOCN, a white, crystalline compound,... 

The word ether is often associated with general anesthetics because of the well-known use of ethyl ether for this purpose. Ethyl ether became generally used as an anesthetic for surgical operations in about 1850. Before that time, surgery was an agonizing procedure. The patient was strapped to a table and (if lucky) soon fainted from the pain. Divinyl ether (vinethene) is an anesthetic that acts more rapidly and is less nauseating than ethyl ether ...
