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.
