Industrial naphthalene, also known as naphthalene, is a colorless and glossy flake crystal. Insoluble in water, easily sublimates, can evaporate with water vapor, and has a special odor. It is the most important polycyclic aromatic hydrocarbon in industry, which can be used to produce phthalic anhydride, water reducing agents, intermediates of dyes, rubber additives, and insecticides. According to different purities, naphthalene can be divided into industrial naphthalene and refined naphthalene. The purity of industrial naphthalene is generally about 96%. After further purification and desulfurization of industrial naphthalene, high-purity refined naphthalene can be obtained.

Due to the difficulty in easing negative factors this week, there are still expectations of a decline in the domestic industrial naphthalene market. Under the continuous losses of the terminal naphthalene phthalic anhydride industry, there is a negative attitude towards the purchase of industrial naphthalene. Although some deep processing enterprises have maintenance plans after the National Day holiday, due to long-term losses, many naphthalene phthalic anhydride enterprises in East China have parked their cars to avoid the market, resulting in a slowdown in demand for industrial naphthalene. After the holiday, it is still necessary to pay attention to the operation of the phthalic anhydride industry. If the loss situation is difficult to alleviate, the resistance of industrial naphthalene will continue to increase in the later stage.
