萘與水混在一起如何分離？精萘廠家分析：萘不溶于水，過(guò)濾即可。但是它易揮發(fā)，易升華，所以不要加熱干燥。

How to separate naphthalene from water when mixed? Refined naphthalene manufacturer analysis: naphthalene is insoluble in water, filtration is sufficient. But it is volatile and prone to sublimation, so do not heat and dry it.

1，水多，萘不多會(huì)成黏糊狀嗎？應(yīng)該是水少才會(huì)出現(xiàn)吧，那就在加點(diǎn)水就OK了。萘幾乎是不溶于水的。

1. Will a lot of water and not much naphthalene form a sticky paste? It should be due to a lack of water, so just add some water and it's okay. Naphthalene is almost insoluble in water.

2，用乙醚萃取。你說(shuō)的工業(yè)萘是有雜質(zhì)的，多數(shù)為有機(jī)雜質(zhì)，這些雜質(zhì)更易溶于有機(jī)溶劑乙醚，那么沒(méi)有達(dá)到除雜的效果。

2. Extract with ether. The industrial naphthalene you mentioned has impurities, most of which are organic impurities. These impurities are more easily soluble in the organic solvent ether, so the impurity removal effect is not achieved.

萘是重要的有機(jī)化工基本原料，廣泛用于生產(chǎn)合成纖維、橡膠、樹(shù)脂、染料、藥物和各種化學(xué)助劑。萘在常溫下是白色固體，易溶于苯類溶劑，難溶于甲醇，易升華，有刺激性氣味。

Naphthalene is an important basic organic chemical raw material, which is widely used in the production of Synthetic fiber, rubber, resin, dyes, drugs and various chemical additives. Naphthalene is a white solid at room temperature, easily soluble in benzene solvents, insoluble in methanol, easily sublimated, and has a pungent odor.

萘主要來(lái)自煤焦油，是煤焦油中重要和含量高的組分(約占煤焦油的10%)

Naphthalene is mainly from Coal tar, which is an important and high content component in Coal tar (accounting for about 10% of Coal tar)

除了含萘以外，煤焦油還含有茶的同系物，即a -甲基萘和β-甲基萘，它們?cè)诿航褂椭械暮糠謩e為0.5%和1. 0%，用途也十分廣泛。

In addition to naphthalene, Coal tar also contains tea homologues, namely, a - methylnaphthalene and β- Methylnaphthalene, their contents in Coal tar are 0.5% and 1 0%, also widely used.

蔡的結(jié)晶溫度與其純度有關(guān)。當(dāng)蔡含有雜質(zhì)時(shí)，其結(jié)晶溫度下降。通常用測(cè)結(jié)晶點(diǎn)的方法，即可知道萘的純度。還有什么想知道的事項(xiàng)就來(lái)我們網(wǎng)站http://yaoguangyi.cn咨詢了解吧！

The crystallization temperature of Cai is related to its purity. When Cai contains impurities, its crystallization temperature decreases. Usually, the purity of naphthalene can be determined by measuring the crystallization point. Anything else you want to know, just come to our website http://yaoguangyi.cn Consult and understand!
