Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone ( >C=O ). It is a colorless, highly volatile , and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops .
Phenacetin (/ f ɪ ˈ n æ s ɪ t ɪ n / ⓘ; acetophenetidin, N-(4-ethoxyphenyl)acetamide [1]) is a pain-relieving and fever-reducing drug, which was widely used following its introduction in 1887. It was withdrawn from medicinal use as dangerous from the 1970s (e.g., withdrawn in Canada in 1973, [ 2 ] and by the U.S. Food and Drug ...
The molecular formula C 6 H 7 NO (molar mass: 109.13 g/mol) may refer to: Aminophenols. 2-Aminophenol; 3-Aminophenol; 4-Aminophenol; Nicotinyl alcohol ...
Diethyl ether has higher water solubility of 8 g per 100 mL, versus diphenyl ether, with a solubility of 0.002 g per 100 mL. [ 3 ] [ 4 ] The presence of the aromatic ring also draws electrons away from the ethereal oxygen, making the hydrolysis of a phenol ether significantly more difficult than that of an alkyl ether. [ 5 ]
(ch 3 c(o)) 2 o + ch 3 c(o)ch 3 → ch 3 c(o)ch 2 c(o)ch 3 A second synthesis involves the base-catalyzed condensation (e.g., by sodium ethoxide CH 3 CH 2 O − Na + ) of acetone and ethyl acetate , followed by acidification of the sodium acetylacetonate (e.g., by hydrogen chloride HCl): [ 11 ]
2-Aminophenol is an organic compound with the formula C 6 H 7 NO. Along with its isomer 4-aminophenol, it is an amphoteric molecule and a reducing agent. It is a useful reagent for the synthesis of dyes and heterocyclic compounds. [3] Reflecting its slight hydrophilic character, white powder is moderately soluble in alcohols and can be ...
