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-Methoxynaphthalene, also called β-naphthol methyl ether or yara yara, [2] is a stabilizer found in gunpowder, particularly smokeless gunpowders. It is soluble in alcohol , and insoluble in water and dipropylene glycol .
Naphthalenesulfonic acids are used in the synthesis of 1-naphthol and 2-naphthol, precursors for various dyestuffs, pigments, rubber processing chemicals and other chemicals and pharmaceuticals. [25] They are also used as dispersants in synthetic and natural rubbers, in agricultural pesticides , in dyes, and in lead–acid battery plates.
2-Naphthalenethiol is an organosulfur compound with the formula C 10 H 7 SH. It is a white solid. It is a white solid. It is one of two mono thiols of naphthalene , the other being 1-naphthalenethiol .
The autoignition temperature of diethyl ether is 160 °C (320 °F). The diffusion of diethyl ether in air is 9.18 × 10 −6 m 2 /s (298 K, 101.325 kPa). [citation needed] Ether is sensitive to light and air, tending to form explosive peroxides. [19] Ether peroxides have a higher boiling point than ether and are contact explosives when dry. [19]
