Refined naphthalene is a colorless and volatile liquid with a naphthalene odor. It is a by-product of the kerosene processing process and is mainly used as an organic synthesis raw material, such as in the production of perylene anhydride, dyes, resins, coatings, pesticides, etc. The production of refined naphthalene is related to the production of light oil products such as kerosene and diesel.

由于环保政策趋严，对重污染能源的限制增加，导致轻质油品的产量增加，进而使得精萘的产量也随之增加。另外，精萘的消费量也随着苝酐行业的发展而增加。苝酐是一种高端染料中间体，主要应用于高端印染、化妆品、保健品等领域。随着人们生活水平的提高，对高端染料的需求也在增加，从而带动了苝酐行业的发展。

Due to stricter environmental policies and increased restrictions on heavily polluting energy sources, the production of light oil products has increased, leading to an increase in the production of refined naphthalene. In addition, the consumption of refined naphthalene has also increased with the development of the perylene anhydride industry. Perylene anhydride is a high-end dye intermediate mainly used in fields such as high-end printing and dyeing, cosmetics, and health products. With the improvement of people's living standards, the demand for high-end dyes is also increasing, which has driven the development of the perylene anhydride industry.

目前，精萘主要依赖进口，国内市场供不应求。预计未来几年，精萘的供需格局将保持紧张。国内市场对精萘的需求主要集中在苝酐行业，而国内苝酐产能占全球苝酐总产能的比例很低，因此国内苝酐企业对精萘的需求量很大。而国内精萘的产量有限，不能满足苝酐企业的需求，因此需要进口精萘来弥补供需缺口。

At present, refined naphthalene mainly relies on imports, and the domestic market is in short supply. It is expected that the supply and demand pattern of refined naphthalene will remain tense in the coming years. The demand for refined naphthalene in the domestic market is mainly concentrated in the Perylene Anhydride industry, and the proportion of domestic Perylene Anhydride production capacity to the global total Perylene Anhydride production capacity is very low. Therefore, domestic Perylene Anhydride enterprises have a large demand for refined naphthalene. However, the production of refined naphthalene in China is limited, which cannot meet the needs of perylene anhydride enterprises. Therefore, it is necessary to import refined naphthalene to fill the supply and demand gap.

综上所述，精萘市场前景广阔，供需格局将保持紧张。对于生产企业来说，需要不断提高产品质量和生产效率，以满足市场需求。同时，还需要关注环保政策的变化，积极推进环保技术和工艺的研发，以降低生产过程中的环境污染和资源浪费。

In summary, the market prospects for refined naphthalene are broad, and the supply and demand pattern will remain tense. For production enterprises, it is necessary to continuously improve product quality and production efficiency to meet market demand. At the same time, it is also necessary to pay attention to changes in environmental policies and actively promote the research and development of environmental protection technologies and processes to reduce environmental pollution and resource waste in the production process.

需要注意的是，精萘是一种有毒物质，对人体健康有害。在使用、储存和运输过程中需要遵守相关安全操作规程，确保人员安全和环境安全。同时，还需要加强对精萘的环境监测和污染治理，防止其对环境造成不良影响。

It should be noted that refined naphthalene is a toxic substance that is harmful to human health. It is necessary to comply with relevant safety operating procedures during use, storage, and transportation to ensure personnel and environmental safety. At the same time, it is necessary to strengthen environmental monitoring and pollution control of refined naphthalene to prevent its adverse impact on the environment.
