精萘是什么?剛聽(tīng)名字的時(shí)候，我們可能會(huì)犯糊涂。其實(shí)它就是一種萘的提純物。根據(jù)萘純度的不同，可以把它分為工業(yè)萘和精萘。工業(yè)萘純度較低，一般約為96%。當(dāng)把工業(yè)萘進(jìn)一步提純，得到含萘98.4596以上，而且結(jié)晶點(diǎn)不低于79.3C的萘產(chǎn)品時(shí)，我們把它叫做精萘。下面精萘廠(chǎng)家為您講解更多產(chǎn)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:

精萘是一種白色而且容易揮發(fā)的晶體，它是工業(yè)中重要的稠環(huán)芳烴，所以同樣具有芳烴的性質(zhì)，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(lái)的粗萘卻有一種煤焦油的臭味。

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，但是易溶于一些有機(jī)溶劑，比如無(wú)水乙醇、醚、苯等。精萘的穩(wěn)定性也比較穩(wěn)定，而且熔點(diǎn)在80.1C，沸點(diǎn)在217.9C。這些理化性質(zhì)，讓它的用途相對(duì)來(lái)說(shuō)比較廣泛。

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間體，尤其被人熟悉的是可以用來(lái)制作樟腦丸。當(dāng)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(hù)劑等。

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.

精萘也常常用于醫(yī)藥領(lǐng)域，比如生產(chǎn)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.

當(dāng)然，精萘的很多用途還有待開(kāi)發(fā)。因?yàn)榫潦菑氖椭刑崛〕鰜?lái)的，屬于低毒類(lèi)的物質(zhì)，我們?cè)谑褂镁恋倪^(guò)程中，也要注意呼吸系統(tǒng)防護(hù)，佩戴過(guò)濾式防毒面具等。您有需求可以隨時(shí)來(lái)我們網(wǎng)站http://mc-downloads.com咨詢(xún)！

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.
