Introduction:
The raw materials for separating and extracting methyl naphthalene are generally wash oil, methyl naphthalene oil and industrial naphthalene bottom oil. The raw materials for extracting methyl naphthalene are processed by rectification method to easily obtain the enriched fraction of methyl naphthalene. Starting from the enriched fraction of methyl naphthalene, there is a limit to purely purifying methyl naphthalene by distillation or crystallization. Therefore, rectification is often used to obtain narrow fractions of methyl naphthalene, and then refined by crystallization or azeotropic distillation.
