Glacial acetic acid physical properties

A summary of the physical properties of glacial acetic acid is given in Table 5. ... 

Physical Properties Phosgene is a colorless gas at room temperature with a density, relative to air, of 3.4. It has mp of — 118°C, bp of 8°C, and vapor pressure of approximately 1200 mm at 20°C. It is slightly soluble in water, in which it hydrolyzes, and rather soluble in most hydrocarbons (e.g., hexane and benzene) and in glacial acetic acid. Phosgene has an odor of newly mown or musty hay. It is estimated that the least detectable odor occurs at approximately 1 ppm, but that the lowest concentration affecting the eyes is about 4 ppm. 

PHYSICAL PROPERTIES Gray or purple crystalline solid insoluble in water soluble in benzene, diethyl ether, ethanol and glacial acetic acid MP (132°C) BP (402°C) VP (1.15E" mm Hg 25°C) SG (not available). 

PHYSICAL PROPERTIES gray to purple crystalline solid readily soluble in diethyl ether, ethanol, benzene, and glacial acetic acid insoluble in water MP (132-133 C, 269.6-271.4"F) BP (420 C, 788°F) VP (1.15 x 10 mmHg at 25 C). 

PHYSICAL PROPERTIES white to light yellow, needle-like, crystalline solid sweet odor insoluble in water readily soluble in hot alcohol, but slightly soluble in cold alcohol very soluble in ether soluble in chloroform, carbon tetrachloride, benzene, acetone, mineral spirits, turpentine, glacial acetic acid, pine oil, and perchloroethylene MP(113-114°C, 235.4-237.2°F) BP(340 C, 644 F at 760 mmHg, 223.7-224.1°C, 434.7-435.4 F at 30 mmHg) DN(1.203 g/cm at 25 C) VD(not applicable) VP(unknown). 

PHYSICAL PROPERTIES colorless to yellow liquid or pale yellow crystals viscous liquid sweet burning taste miscible with ether, acetone, glacial acetic acid, ethyl acetate, pyridine, chloroform, ethylene bromide, benzene, nitrobenzene, and dichloroethylene sparingly soluble in petroleum ether, glycerol and liquid petrolatum practically insoluble in water MP... 

Why is glacial acetic acid designated as "glacial" Hint Consult a handbook of physical properties.)... 

Physical properties. All are colourless crystalline solids except formic acid, acetic acid (m.p. 18 when glacial) and lactic acid (m.p. 18°, usually a syrup). Formic acid (b.p. loo ") and acetic acid (b.p. 118 ) are the only members which are readily volatile lactic acid can be distilled only under reduced pressure. Formic and acetic acids have characteristic pungent odours cinnamic acid has a faint, pleasant and characteristic odour.
