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 other hydroxylamines it will react with aldehydes to form nitrones, illustrative is the condensation with benzaldehyde to form diphenylnitrone, a well-known 1,3-dipolar compound: [4] C 6 H 5 NHOH + C 6 H 5 CHO → C 6 H 5 N(O)=CHC 6 H 5 + H 2 O. Phenylhydroxylamine is attacked by NO + sources to give cupferron: [5] C 6 H 5 NHOH + C 4 H 9 ...
The three aminophenol isomers: Left: 2-Aminophenol (o-aminophenol) Center: 3-Aminophenol (m-aminophenol) Right: 4-Aminophenol (p-aminophenol) Aminophenol may refer to any of three isomeric chemical compounds: 2-Aminophenol; 3-Aminophenol; 4-Aminophenol; They are simultaneously an aniline and a phenol
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 ...
4-Toluenesulfonyl chloride (p-toluenesulfonyl chloride, toluene-p-sulfonyl chloride) is an organic compound with the formula CH 3 C 6 H 4 SO 2 Cl. This white, malodorous solid is a reagent widely used in organic synthesis. [2] Abbreviated TsCl or TosCl, it is a derivative of toluene and contains a sulfonyl chloride (−SO 2 Cl) functional group.
