General Description
Yellow crystals or white powder. Characteristic irritating odor.
Air & Water Reactions
Sensitive to prolonged exposure to air. Insoluble in water.
Reactivity Profile
5,6-BENZOQUINOLINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides.
Fire Hazard
5,6-BENZOQUINOLINE is combustible.
Safety Profile
Mutation data reported. Whenheated to decomposition it emits toxic fumes of NOx.
Purification Methods
Purify as 3,4-benzoquinoline above. The picrate has m 258.1-259o (from EtOH or H2O). [Albert et al. J Chem Soc 2240 1948, Beilstein 20 III/IV 4009, 20/8 V 220.]
