精萘是什么?刚听名字的时候，我们可能会犯糊涂。其实它就是一种萘的提纯物。根据萘纯度的不同，可以把它分为工业萘和精萘。工业萘纯度较低，一般约为96%。当把工业萘进一步提纯，得到含萘98.4596以上，而且结晶点不低于79.3C的萘产品时，我们把它叫做精萘。下面精萘厂家为您讲解更多产品信息：

What is refined naphthalene? When we first hear the name, we may feel confused. In fact, it is a purified substance of naphthalene. According to the purity of naphthalene, it can be divided into industrial naphthalene and refined naphthalene. The purity of industrial naphthalene is relatively low, generally around 96%. When industrial naphthalene is further purified to obtain naphthalene products containing over 98.4596 naphthalene and with a crystallization point not less than 79.3C, we call it refined naphthalene. Below, the refined naphthalene manufacturer will explain more product information to you:

精萘是一种白色而且容易挥发的晶体，它是工业中重要的稠环芳烃，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粗萘却有一种煤焦油的臭味。

Refined naphthalene is a white and easily volatile crystal, which is an important polycyclic aromatic hydrocarbon in industry. Therefore, it also has aromatic properties and a mild and non irritating aromatic odor. On the contrary, crude naphthalene separated from Coal tar has a smell of Coal tar.

精萘不溶于水，但是易溶于一些有机溶剂，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80.1C，沸点在217.9C。这些理化性质，让它的用途相对来说比较广泛。

Refined naphthalene is insoluble in water, but it is easily soluble in some organic solvents, such as anhydrous ethanol, ether, benzene, etc. The stability of refined naphthalene is also relatively stable, with a melting point of 80.1C and a boiling point of 217.9C. These physical and chemical properties make its use relatively broad.

精萘主要用于制造染料的中间体，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。

Refined naphthalene is mainly used as an intermediate for making dyes, especially for making Mothball. Of course, in addition to making Mothball, it is also an important raw material for leather making. It can also be used as a wood protectant, etc.

精萘也常常用于医药领域，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丸，答案是否定的。

Refined naphthalene is also often used in the medical field, such as the production of 1-naphthol, 2-Naphthol and menadine. So as we mentioned earlier, whether refined naphthalene can only be used to make Mothball, 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。您有需求可以随时来我们网站http://www.jnjdbc.cn咨询！

Of course, many uses of refined naphthalene still need to be developed. Because refined naphthalene is extracted from petroleum and belongs to low toxic substances, we should also pay attention to respiratory protection and wear filter Gas mask when using refined naphthalene.
