精萘是一种重要的化工原料，其获取途径主要源于工业生产过程中的提取与加工，需通过一系列工艺从相关原料中分离提纯得到。

　　Refined naphthalene is an important chemical raw material, which is mainly obtained through extraction and processing in industrial production processes. It needs to be separated and purified from related raw materials through a series of processes.

　　从原料来源看，精萘的主要获取渠道与煤焦油加工密切相关。煤焦油是煤炭干馏过程中产生的一种黑色粘稠液体，其中含有多种有机化合物，萘便是其中含量较高的成分之一。在煤焦油的分馏过程中，通过控制温度，可将萘含量较高的馏分分离出来，这一馏分经洗涤、蒸馏等进一步提纯工艺，去除其中的杂质，最终得到精萘。

　　From the perspective of raw material sources, the main channels for obtaining refined naphthalene are closely related to coal tar processing. Coal tar is a black viscous liquid produced during the coal dry distillation process, which contains various organic compounds, among which naphthalene is one of the components with a higher content. In the fractionation process of coal tar, by controlling the temperature, the fraction with high naphthalene content can be separated. This fraction is further purified through washing, distillation, and other processes to remove impurities and ultimately obtain refined naphthalene.

　　除了煤焦油，某些石油加工过程中也可能产生含萘的馏分，不过相较于煤焦油，石油基原料中萘的含量通常较低，因此并非精萘获取的主要途径。此外，在一些化工产品的生产副产物中，也可能含有少量萘，通过特定的回收工艺可将其提取并提纯为精萘，实现资源的二次利用。

　　In addition to coal tar, some petroleum processing processes may also produce naphthalene containing fractions, but compared to coal tar, the naphthalene content in petroleum based raw materials is usually lower, so it is not the main way to obtain refined naphthalene. In addition, some by-products of chemical production may also contain small amounts of naphthalene, which can be extracted and purified into refined naphthalene through specific recycling processes, achieving secondary utilization of resources.

　　精萘的获取过程需经过严格的提纯处理，因为粗萘中含有硫、酚等杂质，这些杂质会影响精萘的纯度和使用性能。提纯工艺包括酸洗、碱洗、蒸馏等步骤，通过逐步去除杂质，使萘的纯度达到相关标准，满足不同行业的使用需求。

　　The process of obtaining refined naphthalene requires strict purification treatment, as crude naphthalene contains impurities such as sulfur and phenol, which can affect the purity and performance of refined naphthalene. The purification process includes steps such as acid washing, alkali washing, and distillation. By gradually removing impurities, the purity of naphthalene reaches relevant standards, meeting the usage needs of different industries.

　　需要注意的是，精萘的获取属于工业生产范畴，其生产、储存和运输都需遵循相关安全规范，以确保操作过程的安全与环保。

　　It should be noted that the acquisition of refined naphthalene belongs to the scope of industrial production, and its production, storage, and transportation must comply with relevant safety regulations to ensure the safety and environmental protection of the operation process.
