1,3-Dicyanobenzene Chemical Properties,Usage,Production

Description

1,3-Dicyanobenzene appears as white, crystalline or flaky solid with an almond-like odor. mp: 161-162 °C (sublimes) Density 1.28 g/cm3 (at 25 °C). Insoluble in water. Soluble in benzene and in acetone. Used as an intermediate in the manufacture of polyurethane paints and varnishes, pharmaceuticals, and agricultural chemicals.

Chemical Properties

off-white to light brown solid

Uses

An intermediate in the manufacture of paints, varnishes, and agricultural chemicals.

Uses

1,3-Dicyanobenzene was used in the synthesis of oxazolines and 1,3-bis-(4,4-dimethyl-2-oxazolinyl)benzene.

Definition

ChEBI: Isophthalonitrile is a nitrile. It is functionally related to an isophthalic acid.

General Description

White, crystalline or flaky solid with an almond-like odor. Mp:161-2°C (sublimes) Density 1.28 g cm-3 (at 25°C). Insoluble in water. Soluble in benzene and in acetone. Used as an intermediate in the manufacture of polyurethane paints and varnishes, pharmaceuticals, and agricultural chemicals.

Reactivity Profile

1,3-Dicyanobenzene is a combustible solid. Emits toxic fumes of NOx and CN- when heated to decomposition. Incompatible with strong oxidizing agents.

Health Hazard

m-Phthalodinitrile is a skin irritant in animals.In humans there have been no reports of adverse effects. The probable reason for lack of systemic effects is that aromatic, unlike aliphatic, nitriles do not liberate cyanide in the body.

Flammability and Explosibility

Not classified

Safety Profile

Poison by ingestion. An eye irritant. When heated to decomposition it emits toxic fumes of NOx and CN-. See also NITRILES.
