Anshan Beida Synthetic Chemicals Factory

White crystals, plates, leaflets or light tan powder. Sublimes readily. Exhibits strong fluorescence and long phosphorescence on exposure to ultraviolet light.

Colorless to off-white crystalline solid. Odor threshold 1 ppm. Taste threshold 0.001 mg/L.

White needles. Melting point 93.6°C. Soluble in hot alcohol. Denser than water and insoluble in water. Hence sinks in water. May irritate skin and mucous membranes. Emits acrid smoke and irritating fumes when heated to decomposition. Derived from coal tar and used to make dyes, pharmaceuticals, insecticides, fungicides, and plastics.

Colorless monoclinic crystals with a faint aromatic odor. Solutions exhibit a blue fluorescence.

White leaflets. Sublimes easily under a vacuum. Fluorescent when impure.

Colorless liquid. Freezing point -22°C (7.6°F). Boiling point 240-243°C (464-469°F). Flash point 82°C (180°F). Denser than water. Derived from coal tar and used in organic synthesis.

Naphthalene is an organic compound with formula C ₁₀H ₈. It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass.

A colorless liquid with a peculiar odor. Slightly denser than water. Contact may irritate to skin, eyes, and mucous membranes. May be toxic by ingestion. Used to make other chemicals.

White crystalline solid.

A colorless oily liquid darkening to red-brown on exposure to air. Flash point 175°F. Denser than water and slightly soluble in water. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion. Used to make dyes, pharmaceuticals and other chemicals.

A clear colorless liquid with a pleasant odor. Flash point 180°F. Insoluble in water. Vapors are heavier than air. Used to manufacture other chemicals and as a fungicide.

A clear colorless to light yellow liquid with a penetrating nauseating odor. Density 0.978 g / cm3. Flash point 68°F. Vapors are heavier than air. Toxic by ingestion and inhalation. Combustion produces toxic oxides of nitrogen.
