Introduction:
The wash oil fraction is the cut with the widest cutting temperature range in coal tar distillation. The cutting temperature range is usually 230~300℃. The wash oil fraction is between the naphthalene oil and anthracene oil fractions and is basically composed of two-ring and three-ring compounds. Wash oil is mainly used for washing and absorbing benzene compounds in coal gas, hence the name.
