What is anthracene oil? What are the characteristics and uses?

Anthracene oil is a part of coal tar. Tar distills fractions at 280~360℃: the initial distillation points of the first-class anthracene oil and the second-class anthracene oil are 365 and 438+00℃ respectively, and when 50% of them are removed, the initial distillation point is 400℃.

CASNo.: 120- 12-7

Molecular formula: C 14H 10.

Molecular weight: 178.22

Yellow-green oily liquid, crystallized at room temperature, with yellow and blue fluorescence, soluble in ethanol and ether, insoluble in water, partially soluble in hot benzene, chlorobenzene and other organic solvents, with strong irritation. Anthracene is flammable at high temperature, with melting point 2 17℃, density 1.24g/ml, boiling point 345℃, spontaneous combustion point 540℃ and flash point12/.1℃ (closed. It can be used to make anthraquinone dyes, synthetic tanning agents and paints.

The main components of this product are anthracene, phenanthrene, fluorene, acenaphthene and carbazole.

Preparation: Distilling tar to cut fractions at 280~360℃. The yield: the initial distillation points of anthracene oil and anthracene oil are 365,438+00℃ respectively, and 400℃ when 50% of them slip out.

Uses: It is the raw material for manufacturing coatings, electrodes, pitch coke, carbon black, wood preservative oil and pesticides, and is mainly used for extracting crude anthracene, acenaphthene, fluorene, phenanthrene, carbazole and other chemical raw materials. Used to prepare carbon black raw oil, road asphalt or fuel oil, etc. It can also be used for wood preservation and preparation.

By sea: train tanker.
