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.

精萘是一種白色而且容易揮發的晶體，它是工業中更重要的稠環芳烴，所以同樣具有芳烴的性質，有一種溫和不刺激的芳香氣味。與之相反的，從煤焦油里面分離出來的糊萘卻有一種煤焦油的身味。精萘不溶干水，但是易溶干一些有機溶劑，比如無水乙醇、醚、苯等。精萘的穩定性也比較穩定，而且熔點在80.1℃，沸點在217.9℃。這些理化性質，讓它的用途相對來說比較廣泛。

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間體，尤其被人熟悉的是可以用來制作樟腦丸。當然，除了制作樟腦丸外，它還是皮革的重要制作原料。它還可以用作木材保護劑等。精萘也常常用干醫藥領域，比如生產1-萘酚、2-萘酚和甲萘胺等等。所以我們前面提到的，精萘是不是只可以制作樟腦為，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.

當然，精萘的很多用途還有待開發。因為精萘是從石油中提取出來的，屬于低毒類的物質，我們在使用精萘的過程中，也要注意呼吸系統防護，佩戴過濾式防毒面具等。

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.
