Introductions of 2-Naphthol
2-naphthol is mainly used in the production of various dye intermediates, such as H acid, J acid, Tobias acid, gamma acid, etc. The main raw material is naphthalene. The price is mainly affected by naphthalene. At the same time, 2-naphthol production needs to use a lot of H2SO4 98% and NaOH, and whether treating wastewater well is the key for enterprises to obtain strong competitiveness.
In order to obtain a larger market, some enterprises in China will take the initiative to advance to the downstream industry chain. For example, in the production of 2-naphthol at the same time, the production of intermediate products such as BON Acid and Naphthol-AS, as well as orangic pigments and other downstream products.
In this way, enterprises can gain more initiative in the market.
