萘与水混在一起如何分离？精萘厂家分析：萘不溶于水，过滤即可。但是它易挥发，易升华，所以不要加热干燥。

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，萘不多会成黏糊状吗？应该是水少才会出现吧，那就在加点水就OK了。萘几乎是不溶于水的。

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。你说的工业萘是有杂质的，多数为有机杂质，这些杂质更易溶于有机溶剂乙醚，那么没有达到除杂的效果。

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.

萘是重要的有机化工基本原料，广泛用于生产合成纤维、橡胶、树脂、染料、药物和各种化学助剂。萘在常温下是白色固体，易溶于苯类溶剂，难溶于甲醇，易升华，有刺激性气味。

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.

萘主要来自煤焦油，是煤焦油中重要和含量高的组分(约占煤焦油的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，煤焦油还含有茶的同系物，即a -甲基萘和β-甲基萘，它们在煤焦油中的含量分别为0.5%和1. 0%，用途也十分广泛。

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.

蔡的结晶温度与其纯度有关。当蔡含有杂质时，其结晶温度下降。通常用测结晶点的方法，即可知道萘的纯度。还有什么想知道的事项就来我们网站http://www.jnjdbc.cn咨询了解吧！

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://www.jnjdbc.cn Consult and understand!
