This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Like most ketones, acetone exhibits the keto–enol tautomerism in which the nominal keto structure (CH 3) 2 C=O of acetone itself is in equilibrium with the enol isomer (CH 3)C(OH)=(CH 2) (prop-1-en-2-ol). In acetone vapor at ambient temperature, only 2.4 × 10 −7 % of the molecules are in the enol form. [46] In the presence of suitable ...
In addition acetanisole can sometimes smell like butter or caramel. [3] Its chemical names are based on considering the structure as either an acetyl ( methyl - ketone ) analog of anisole . Other names It can also be seen as a methyl ether analog of acetophenone .
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 ]
In one such application, the wavelength of the fluorescence of peptide-coated carbon nanotubes was found to change when exposed to explosives, facilitating detection. [3] However, more recently the small chromophore solvatochromism hypothesis has been challenged for carbon nanotubes in light of older and newer data showing electrochromic behavior.
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 ...
