This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
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.
For example, carboxylic acids such as acetic acid (ethanoic acid) or benzoic acid form dimers in benzene, so that the number of solute particles is half the number of acid molecules. When solute particles dissociate in solution, i is greater than 1 (e.g. sodium chloride in water, potassium chloride in water, magnesium chloride in water).
Sulfonation gives the "alpha" product naphthalene-1-sulfonic acid as the kinetic product but naphthalene-2-sulfonic acid as the thermodynamic product. The 1-isomer forms predominantly at 25 °C, and the 2-isomer at 160 °C. Sulfonation to give the 1- and 2-sulfonic acid occurs readily: H 2 SO 4 + C 10 H 8 → C 10 H 7 SO 3 H + H 2 O
1-Naphthaleneacetic acid (NAA) is an organic compound with the formula C 10 H 7 CH 2 CO 2 H. This colorless solid is soluble in organic solvents. This colorless solid is soluble in organic solvents. It features a carboxylmethyl group (CH 2 CO 2 H) linked to the "1-position" of naphthalene .
In one method, naphthalene is nitrated to give 1-nitronaphthalene, which is hydrogenated to the amine followed by hydrolysis: C 10 H 8 + HNO 3 → C 10 H 7 NO 2 + H 2 O C 10 H 7 NO 2 + 3H 2 → C 10 H 7 NH 2 + 2H 2 O C 10 H 7 NH 2 + H 2 O → C 10 H 7 OH + NH 3. Alternatively, naphthalene is hydrogenated to tetralin, which is oxidized to 1 ...
Hydrogen cyanide is a weak acid in aqueous solution with a pK a of about 9. In strongly alkaline solutions, above pH 11, say, it follows that sodium cyanide is "fully dissociated" so the hazard due to the hydrogen cyanide gas is much reduced. An acidic solution, on the other hand, is very hazardous because all the cyanide is in its acid form.
