精萘的生产主要依赖于工业萘的提纯过程，目前常用的生产工艺包括区域熔融法、分步结晶法、催化加氢法和动态结晶法等。其中，分步结晶法和动态结晶法因其高效性和低能耗的特点，成为近年来研究的热点。例如，乳化结晶法通过使用特定的乳化剂和辅助剂，能够有效提高精萘的产率和质量，实验表明其产率可达到90%以上。

The production of refined naphthalene mainly relies on the purification process of industrial naphthalene. Currently, commonly used production processes include regional melting method, stepwise crystallization method, catalytic hydrogenation method, and dynamic crystallization method. Among them, the stepwise crystallization method and dynamic crystallization method have become hot research topics in recent years due to their high efficiency and low energy consumption. For example, the emulsion crystallization method can effectively improve the yield and quality of refined naphthalene by using specific emulsifiers and adjuvants, and experiments have shown that its yield can reach over 90%.

除了传统的物理方法，化学方法如催化加氢法也在不断优化。该方法通过在催化剂的作用下，将工业萘中的杂质转化为易于分离的副产物，从而提高精萘的纯度。近年来，研究者还尝试将动态结晶与静态结晶相结合，以进一步提升精萘的生产效率和产品质量。

In addition to traditional physical methods, chemical methods such as catalytic hydrogenation are also constantly being optimized. This method improves the purity of refined naphthalene by converting impurities in industrial naphthalene into easily separable by-products under the action of a catalyst. In recent years, researchers have also attempted to combine dynamic crystallization with static crystallization to further improve the production efficiency and product quality of refined naphthalene.

随着技术的不断进步，精萘的生产工艺正朝着更高效、更环保的方向发展。未来，随着新技术的推广应用，精萘的生产成本将进一步降低，同时其产品质量也将得到进一步提升，为下游产业提供更优质的原料支持

With the continuous advancement of technology, the production process of refined naphthalene is developing towards a more efficient and environmentally friendly direction. In the future, with the promotion and application of new technologies, the production cost of refined naphthalene will be further reduced, and its product quality will also be further improved, providing higher quality raw material support for downstream industries
