精萘是什么？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98.45%以上，而且结晶点不低于79.3℃的萘产品时，我们把它叫做精萘。那么精萘是不是只可以用来制作樟脑丸呢？精萘厂家来简单讲一下：

What is refined naphthalene? In fact, it is a kind of naphthalene purification. According to the purity of naphthalene, it can be divided into industrial naphthalene and refined naphthalene. The purity of industrial naphthalene is 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 not lower than 79.3 ℃, we call it refined naphthalene. So can refined naphthalene only be used to make camphor pills? The refined naphthalene manufacturer will briefly introduce:

白色易挥发晶体，有温和芳香气味，粗萘有煤焦油臭味；蒸汽压0.13kPa/52.6℃闪点：80℃；熔点80.1℃沸点217.9℃；不溶于水，溶于无水乙醇、醚、苯，相对密度（水=1）1.16；相对密度（空气=1）4.42；稳定性：稳定；危险标记：8（易燃固体）；主要用途：用于制造染料中间体、樟脑丸、皮革、木材保护剂等

White volatile crystal with mild aromatic smell, and crude naphthalene with coal tar odor; Vapor pressure 0.13kPa/52.6 ℃ Flash point: 80 ℃; Melting point 80.1 ℃, boiling point 217.9 ℃; It is insoluble in water, soluble in anhydrous ethanol, ether and benzene, and its relative density (water=1) is 1.16; Relative density (air=1) 4.42; Stability: stable; Hazard mark: 8 (flammable solid); Main uses: used for manufacturing dye intermediates, camphor balls, leather, wood protectants, etc

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。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80.1℃，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 an important polycyclic aromatic hydrocarbon in industry, so it also has the properties of aromatic hydrocarbon, and has a mild and non-stimulating aromatic smell. On the contrary, crude naphthalene separated from coal tar has a smell of coal tar. Refined naphthalene is insoluble in water, but soluble in some organic solvents, such as anhydrous ethanol, ether, benzene, etc. The stability of refined naphthalene is also relatively stable, and its melting point is 80.1 ℃ and boiling point is 217.9 ℃. These physical and chemical properties make it relatively widely used.

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。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 mainly used as an intermediate in the manufacture of dyes, and is especially familiar with the production of camphor pills. Of course, in addition to making camphor pills, 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 pharmaceutical field, such as the production of 1-naphthol, 2-naphthol and methylnaphthylamine. So, as we mentioned earlier, whether refined naphthalene can only be made into camphor pills, 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。您有什么需求就来我们网站http://www.jnjdbc.cn咨询吧！

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 system protection and wear filtered gas masks when using refined naphthalene.
