Methylnaphthalene(CAS NO 1321-94-4)
Preparation and application:
The washi oil fraction is distilled to obtain a mixed methylnaphthalene fraction of 230 ~ 245 ° C, that is, industrial methylnaphthalene. Mixed methyl naphthalene (mMN) can be used as a raw material for the production of pharmaceuticals and surfactants. In addition, methyl naphthalene can be treated with HF / BF3 to prepare mesophase pitch. Mesophase pitch is a high-quality raw material for the preparation of carbon fibers.
