How to distinguish the purity of magnesium chloride

Magnesium Chloride | 2021-07-29

CNow many consumers find that the quality of magnesium chloride in the market is uneven and the quality can not be guaranteed. The quotation of magnesium chloride of different quality varies greatly.

We suggest not to take the price as a step in purchasing magnesium chloride. Generally, there are many impurities in inferior magnesium chloride, which is usually called salt impurities. It will not react with magnesium oxide when mixed into magnesium chloride.

These impurities will not only cause high cost, but also have a harmful impact on the products produced, which is an important problem affecting the product quality.

Magnesium chloride manufacturers have a very simple method to distinguish the purity of magnesium chloride, because most salt impurities are insoluble in water, while magnesium chloride is completely soluble in water. At this time, you can take a small part of magnesium chloride and put it in water, which will produce white precipitation and salt impurities. The more precipitates produced, the lower the purity.

Magnesium chloride is a common chemical product in chemical industry. In order to integrate into the development trend of manufacturing industry, continue to develop commodities. Because of the different water content, the key products sold on the market are magnesium chloride and magnesium chloride hexahydrate. Magnesium chloride is a transparent hexagonal crystal with gloss. Compared with magnesium chloride hexahydrate, the deliquescence is stronger. There is little difference in chemical properties between magnesium chloride and magnesium chloride hexahydrate.

It is commonly used in manufacturing magnesium metal materials and chemical plants, and decorative building materials are widely used. So, what is the method to distinguish magnesium chloride? What identification method does magnesium chloride have?

1. Heat transfer medium:

The detailed actual operation of heat transfer medium is to put a small amount of magnesium chloride into the test tube for heating. Because magnesium chloride does not contain water molecules, there are no water droplets on the inner wall of the test tube during heating, that is, magnesium chloride.

2. Method of measuring content:

It is accurate to distinguish magnesium chloride by this method. However, due to the technical nature of the actual operation method, it is only briefly introduced in detail. In fact, standard manufacturers can apply this method.

3. Appearance identification method:

Magnesium chloride is generally milky white powder or solid in appearance, while magnesium chloride with water molecules is generally crystal in appearance, and magnesium chloride hexahydrate with powder in appearance is not naturally removed.

4. Weighing method:

Relatively speaking, the method of weighing the difference is relatively simple. Because magnesium chloride does not contain crystalline water droplets, the net weight during weighing will be different from that of magnesium chloride with other aqueous molecules.
