Basic Info

What is Magnesium Acetate Tetrahydrate?

Magnesium acetate tetrahydrate is a colorless crystalline solid at space temperature level and stress. Magnesium acetate is an essential generalized steel magnesium organic substance. Usual magnesium acetate has two states: one is anhydrous magnesium acetate, as well as the various other is magnesium acetate tetrahydrate with crystal water. Magnesium acetate tetrahydrate is a The metal-organic substance is simple to synthesize, has high purity, affordable as well as high added value. Magnesium acetate tetrahydrate is a moisturized type of anhydrous magnesium acetate, as a salt type of magnesium, magnesium acetate is just one of the bioavailable forms of magnesium and also creates an extremely water-soluble substance. Magnesium acetate tetrahydrate can be utilized as an electrolyte supplement or as a reagent in molecular biology experiments. Magnesium acetate tetrahydrate is prone to deliquescence when left inside for a long time. Magnesium acetate tetrahydrate is a metal facility that can be utilized as a catalyst, feed additive and cosmetics. It can additionally be utilized as a logical reagent to prepare magnesium acetate. To figure out the salt content of a compound.

The major manufacturing methods are: stemmed from the reaction of magnesium carbonate and also acetic acid. Add 80% acetic acid right into water, heat to 60-80 ° C, and also add magnesium carbonate in small amounts until the co2 no longer gets away. The service was put on a water bathroom and warmed and also concentrated to a relative thickness of 1.25-1.26, after that cooled. The crystals were filtered off to obtain magnesium acetate tetrahydrate. It is acquired by co-heating magnesium nitrate and acetic acid. Magnesium oxide is created by reacting with acetic acid. Steel magnesium as well as acetic acid response in the system.

Magnesium Acetate Tetrahydrate Uses

Application of Magnesium Acetate Tetrahydrate

Magnesium acetate is an important organometallic compound, which can be used as an organic synthesis intermediate, catalyst, analytical reagent, and also as a nano-oxide precursor for preparing magnesium. Magnesium acetate can be fully ground with oxalic acid for 2 hours, dried in an oven at 80°C for 4 hours, and then fired at 600°C for 3 hours to obtain nano-magnesia with an average particle size of 15nm. This method is called solid-phase synthesis of nano-magnesia; Magnesium acetate water can also be used as an organic complex precursor to synthesize nano-magnesium oxide. As a new type of multifunctional non-material, nano-magnesium oxide has a particle size between 1 and 100 nm, a large specific surface area, and a large surface activity. Features such as surface effect, volume effect and quantum tunneling effect. Because nano-magnesia exhibits many special and excellent functions in catalysis, optics, magnetism, mechanics, etc., it has very important application value. In recent years, the industry has set off an upsurge of research on nano-magnesia materials. The preparation method of magnesium oxide nanopowder comprises step 1) drying magnesium acetate at 100°C for 3 to 5 hours to remove crystal water; step 2) dissolving anhydrous magnesium acetate at a ratio of 0.1 to 50:100 In absolute ethanol, a uniform and stable magnesium acetate solution is formed; Step 3) The magnesium acetate solution is continuously atomized and sprayed in the combustion chamber, and a combustion-supporting gas is introduced into the combustion chamber at the same time; the substances in the combustion chamber are continuously ignited to obtain combustion powder body; step 4) collect the combustion powder; roast and mineralize the collected combustion powder in a muffle furnace at a temperature of 400-800°C for 1-3 hours; step 5) cool the mineralized powder to At room temperature, magnesium oxide nanopowder is obtained.

In addition, magnesium acetate tetrahydrate is an easy-to-synthesize metal-organic compound with high purity, low cost and high added value. At the same time, because it has good water solubility, is non-toxic and harmless, and is a green chemical product, it is very promising to vigorously develop its application. China’s magnesium reserves account for 20% of the world’s total. Magnesium carbonate, magnesium chloride and magnesium oxide commonly found in nature can be used as basic raw materials for the synthesis of magnesium acetate tetrahydrate. It is of great practical significance to study new process conditions in depth. In recent years, many special properties of magnesium acetate tetrahydrate are attracting people’s attention, such as having broad application prospects in chemical industry, materials, medicine, agriculture and other fields. Studies have found that magnesium acetate tetrahydrate can be widely used as intermediates, catalysts, analytical reagents, deicing agents, modifiers, etc. in organic synthesis.

Preparation of Magnesium Acetate Tetrahydrate

Anhydrous magnesium acetate can be prepared by reacting magnesium with acetic acid. First, the magnesium ingots are planed into magnesium flakes with a planer. Then wash with hydrochloric acid and 10% sodium hydroxide solution to remove dirt. Finally, it was washed three times with absolute ethanol, dried, and set aside. The experimental device for synthesizing magnesium acetate is carried out in a 250mL four-necked flask. The device is equipped with an electric stirrer, a thermometer, a balance feeder, a vertical glass jacket condenser, and the upper end of the condenser is connected to the drying tower. The reaction solution was heated with an electric heating mantle. Add 4g of magnesium flakes and a small amount of acetic acid into the four-neck flask, start stirring, and heat up. When the temperature reaches 50°C, bubbles are generated in the reaction solution, indicating that the reaction has occurred, so stop heating. Because the reaction is a strong exothermic reaction, the reaction is violent, and a large amount of heat and hydrogen are released during the reaction, so the temperature of the reaction solution can be automatically raised to 120 ° C during the reaction, and the reaction continues under reflux. In order to prevent the reaction from being too violent and dangerous, a balance feeder was used to add the remaining amount of acetic acid dropwise to the reactor equipped with magnesium flakes during the experiment. The reaction process was completed within 2h, and a milky white liquid was obtained. After the reaction solution was left for 12 hours, a white precipitate appeared. Filtration through a vacuum funnel yielded a white magnesium acetate solid. The filtrate was evaporated and dried at 130°C, and a white magnesium acetate solid could be further obtained. The prepared magnesium acetate will deliquesce after being placed in the air for a period of time to generate magnesium acetate tetrahydrate. Calcining it at 140°C for 1 hour can remove the water of crystallization and re-obtain magnesium acetate solid without crystal water.
