2-Nitrobiphenyl Usage And Synthesis

Chemical Properties

Clear yellow liquid after melting. Insoluble in water, soluble in methanol, ethanol, acetone, dimethylformamide, and tetrahydrofurfuryl alcohol.

Uses

2-Nitrobiphenyl is used as a plasticizer for resins, cellulose acetate, cellulose nitrate, and polystyrenes; as a fungicide for textiles; as a wood preservative; and as a dye intermediate.

Synthesis Reference(s)

Tetrahedron Letters, 36, p. 6567, 1995 DOI: 10.1016/0040-4039(95)01327-E

General Description

Gold to tan crystals or brown solid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Aromatic nitro compounds, such as 2-Nitrodiphenyl, range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.

Fire Hazard

2-Nitrodiphenyl is combustible.

Purification Methods

Crystallise it from EtOH (seeding required). Sublime it under vacuum. [Beilstein 5 H 582, 5 I 273, 5 II 487, 5 III 1750.]
