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.
Sodium naphthalene is an organic salt with the chemical formula Na + [C 10 H 8] −. In the research laboratory, it is used as a reductant in the synthesis of organic, organometallic , and inorganic chemistry.
The result is that in dilute ideal solutions, the extent of boiling-point elevation is directly proportional to the molal concentration (amount of substance per mass) of the solution according to the equation: [2] ΔT b = K b · b c. where the boiling point elevation, is defined as T b (solution) − T b (pure solvent).
Molar mass: 128.174 g·mol −1 ... numbered 1, 4, 5, ... Where required, crude naphthalene can be further purified by recrystallization from any of a variety of ...
In water solutions containing relatively small quantities of dissolved solute (as in biology), such figures may be "percentivized" by multiplying by 100 a ratio of grams solute per mL solution. The result is given as "mass/volume percentage". Such a convention expresses mass concentration of 1 gram of solute in 100 mL of solution, as "1 m/v %".
1,5-Dihydroxynaphthalene is prepared from naphthalene-1,5-disulfonic acid by hydrolysis with strong base followed by acidification. It couples with various aryl diazonium salts to give diazo dyes. Oxidation with chromium trioxide gives juglone, a naturally occurring dye. [2] In supramolecular chemistry, 1,5-dihydroxynaphthalene is a popular ...
1-Naphthol, or α-naphthol, is an organic compound with the formula C 10 H 7 OH. It is a fluorescent white solid. 1-Naphthol differs from its isomer 2-naphthol by the location of the hydroxyl group on the naphthalene ring. The naphthols are naphthalene homologues of phenol. Both isomers are soluble in simple organic solvents. They are ...
