Nauseating odors

Colorless hygroscopic liquid with a nauseating odor similar to ammonia and detectable at 0.011-0.04 ppm. This material is hazardous through inhalation, skin absorption, penetration through broken skin, and ingestion, and produces local skin/eye impacts. 

The nauseating odor of DBAE may provide adequate warning of overexposure, because it is unlikely that individuals would stay in badly contaminated areas for any length of time. ... 

An attempt by a laboratory worker to remove animals from an inhalation chamber containing approximately 100 ppm resulted in nausea and vomiting within 5 minutes after a fleeting exposure no irritation of the eyes or throat was noted during this brief exposure. Other persons in the same room also complained of a nauseating odor but showed no ill effects. 

Xenon Difluoride. XeF2 mw 169.30 colorl linear cryst with a body-centered tetragonal cell structure, possessing a nauseating odor mp 129.03 0.05° d 4.32g/cc. V sol in liq anhydr HF moderately sol in w. Prepn is by reacting two moles of Xe with one mole of fluorine in a Ni or Monel vessel at 400°, quenching the reaction at RT, and isolating the product by vac sublimation. Ref 2 lists nine other techniques for the prepn of the difluoride. The pure compd is stable and can be kept indefinitely in Ni or Monel containers... 

Sodium cyanide solution dissolves certain metals (I) with absorption of oxygen, e.g.. gold, silver, mercury, lead, and (2) with evolution of hydrogen, e.g.. copper, nickel, iron. zinc, aluminum, magnesium and solid sodium cyanide, when heated with certain oxides, e.g.. lead monoxide PhO. stannic oxide SnO.. yields the metal of the oxide, e.g.. lead. tin. respectively. and sodium cyanate NaCNO. Two classes of esters arc known, cyanides or nitriles, and isocyanides, isonitriles or carbylatnincs. the latter being very poisonous and of marked nauseating odor... 

Dimethyl Disulfide. DMDS has a nauseating odor and solubility of 3.4g/l in water at 25 °C (40). It is particularly resistant to uncatalyzed oxidation. Its oxidation product—methyl sulfonic acid (CH3S03H)—is odorless, nontoxic, nonvolatile and water soluble.

The boiling point (extrapolated) is 87° and the Trouton s constant is 19.6 cal/deg mole. The compound is fairly stable at room temperature when sealed in a Pyrex glass tube and is easy to handle under vacuum conditions, although care should be taken because of its nauseating odor. 

Disulfur dichloride, S2CI2, is one of the products of the reaction of sulfur with chlorine. A yellow, toxic liquid with a nauseating odor, disulfur dichloride is used mainly for the vulcanization of rubber. 

Properties Colorless oil garliclike, nauseating odor. D1.802(llC) bpl58C(10 mm Hg). Oxidizes in air and forms colorless crystals. Soluble in acetone, benzene, ether. 

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. 

Digermyl sulfide is a colorless liquid with a vapor pressure of 1 mm. at 0°, and an intense, nauseating odor. It is stable for short periods at room temperature in the absence of air and moisture but is best stored in sealed ampuls at liquid-nitrogen temperature. The n.m.r. spectrum has a single line at i4.64. 

Identified in roasted coffee by Merritt et al. (1970) and in stinking green beans by Vincent et al. (1976). Butane has a sweet-nauseating odor, perceptible only in relative high concentration (Arctander, 1967). 

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

Colorless crystals, mp —70° colorless liq. very unstable, dec below — I O 1 on exposure to air. Slight traces of iron carbonyls impart a red or yellow color. Gas has extremely nauseating odor. Sol in alkalies neutral aq solns of salts unstable at room temp strongly alkaline solns of salts, e g. K2Fe-(CO)4. are stable at room temp when all traces of air are excluded but dec gradually at 100 to CO and H2. 

The pure solid hydride is completely colorless and crystalline it melts at —26.2°C to a light-yellow solution which changes to dark yellow at slightly higher temperature (beginnii of decomposition to [Co(CO)4]g. In gas form Co(CO)4H has a nauseating odor and is extremely toxic.
