What is naphthalene? When we first hear the name, we may be confused. In fact, it is a kind of purified naphthalene. According to the different purity of naphthalene, it can be divided into industrial naphthalene and refined naphthalene. The purity of naphthalene in T industry is relatively low, generally about 96%. When industrial naphthalene is further purified to obtain naphthalene products containing more than 98.45% naphthalene and with a crystallization point of not less than 79.3 ℃, we call it refined naphthalene. Can refined naphthalene only be used to make camphor pills? Let's briefly introduce it.

精萘是一种白色而且容易挥发的晶体，它是工业中更重要的稠环芳烃，所以同样具有芳烃的性质，有一种温和不刺激的芳香气味。与之相反的，从煤焦油里面分离出来的糊萘却有一种煤焦油的身味。精萘不溶干水，但是易溶干一些有机溶剂，比如无水乙醇、醚、苯等。精萘的稳定性也比较稳定，而且熔点在80.1℃，沸点在217.9℃。这些理化性质，让它的用途相对来说比较广泛。

Refined naphthalene is a white and volatile crystal. It is a more important polycyclic aromatic hydrocarbon in industry, so it also has the property of aromatic hydrocarbon and has a mild and non irritating aromatic smell. On the contrary, the paste naphthalene separated from coal tar has a body odor of coal tar. Refined naphthalene is insoluble in water, but it is easy to dissolve and dry some organic solvents, such as absolute ethanol, ether, benzene, etc. The stability of refined naphthalene is also relatively stable, and the melting point is 80.1 ℃ and the boiling point is 217.9 ℃. These physical and chemical properties make it relatively widely used.

精萘主要用干制造染料的中间体，尤其被人熟悉的是可以用来制作樟脑丸。当然，除了制作樟脑丸外，它还是皮革的重要制作原料。它还可以用作木材保护剂等。精萘也常常用干医药领域，比如生产1-萘酚、2-萘酚和甲萘胺等等。所以我们前面提到的，精萘是不是只可以制作樟脑为，答案是否定的。

Refined naphthalene is mainly used as an intermediate in the manufacture of dyes, especially for camphor pills. Of course, in addition to making camphor balls, it is also an important raw material for leather. It can also be used as wood protectant. Refined naphthalene is also often used in the field of dry medicine, such as the production of 1-naphthol, 2-naphthol and methylnaphthylamine. Therefore, as we mentioned earlier, whether refined naphthalene can only be used to make camphor, the answer is No.

当然，精萘的很多用途还有待开发。因为精萘是从石油中提取出来的，属于低毒类的物质，我们在使用精萘的过程中，也要注意呼吸系统防护，佩戴过滤式防毒面具等。

Of course, many uses of refined naphthalene have yet to be developed. Because refined naphthalene is extracted from oil and belongs to low toxic substances, we should also pay attention to respiratory protection and wear filter gas masks in the process of using refined naphthalene.
