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. Further sulfonation give di-, tri-, and tetrasulfonic acids.
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.
2-Naphthol, or β-naphthol, is a fluorescent colorless (or occasionally yellow) crystalline solid with the formula C 10 H 7 OH. It is an isomer of 1-naphthol , differing by the location of the hydroxyl group on the naphthalene ring.
