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.

由于環(huán)保政策趨嚴，對重污染能源的限制增加，導致輕質(zhì)油品的產(chǎn)量增加，進而使得精萘的產(chǎn)量也隨之增加。另外，精萘的消費量也隨著苝酐行業(yè)的發(fā)展而增加。苝酐是一種高端染料中間體，主要應用于高端印染、化妝品、保健品等領域。隨著人們生活水平的提高，對高端染料的需求也在增加，從而帶動了苝酐行業(yè)的發(fā)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，精萘主要依賴進口，國內(nèi)市場供不應求。預計未來幾年，精萘的供需格局將保持緊張。國內(nèi)市場對精萘的需求主要集中在苝酐行業(yè)，而國內(nèi)苝酐產(chǎn)能占全球苝酐總產(chǎn)能的比例很低，因此國內(nèi)苝酐企業(yè)對精萘的需求量很大。而國內(nèi)精萘的產(chǎn)量有限，不能滿足苝酐企業(yè)的需求，因此需要進口精萘來彌補供需缺口。

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.

綜上所述，精萘市場前景廣闊，供需格局將保持緊張。對于生產(chǎn)企業(yè)來說，需要不斷提高產(chǎn)品質(zhì)量和生產(chǎn)效率，以滿足市場需求。同時，還需要關注環(huán)保政策的變化，積極推進環(huán)保技術和工藝的研發(fā)，以降低生產(chǎn)過程中的環(huán)境污染和資源浪費。

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，精萘是一種有毒物質(zhì)，對人體健康有害。在使用、儲存和運輸過程中需要遵守相關安全操作規(guī)程，確保人員安全和環(huán)境安全。同時，還需要加強對精萘的環(huán)境監(jiān)測和污染治理，防止其對環(huán)境造成不良影響。

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.
