5,6-BENZOQUINOLINE Chemical Properties,Usage,Production

Chemical Properties

BROWN CRYSTALLINE POWDER

Uses

As a reagent for the determination of cadmium which is pptd as (C13H9N)2H2(CdI4) from dil nitric or sulfuric acid solution in the presence of potassium iodide.

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.]
