Definition:   

Wash oil is an important process of coal tar distillation fractions, one of about 6.5-10% coal tar is a complex mixture, rich in quinoline, isoquinoline, indole, α-Anaphthalene, β-methyltea, biphenyl, dimethyl tea, acenaphthene, fluorene and fluorene oxygen and other valuable

 organic chemical raw materials.

Characters:

   Brown oily liquid, boiling range 230-300 °C, the main component are methyl naphthalene, biphenyl, indole, acenaphthene and so on.Is a combustible items.

Uses:

Currently used mainly for cleaning coke oven gas from the benzene or naphthalene.

As the separation and extraction biphenyl, methyl naphthalene, acenaphthene, fluorene,

 dibenzofurans and other products of raw materials, 

used to absorb benzene.In addition, for the preparation of anti-corrosion oil, production of quinoline, indole, dispersants, water reducing agent.
