Monobasic sodium phosphate and sodium dihydrogen phosphate

Monosodium phosphate is a chemical composition that appeared in the form of solid crystals or white, odorless powder at room temperature. NaH2PO4 is the chemical formula of this salt and it is a combination of sodium and phosphorus.

MSP Mono Sodium Phosphate is used in various products, especially in the dental industry to repair teeth, prevent decay, or as a protector of tooth enamel. it is soluble in water but incompatible with ethanol and ether and creates heterogeneous mixtures with them.

It is an important compound in the human body and changes in its amount and Its concentration in the body can cause disease. The function of this salt in the body is to help regulate rapid fluctuations in acidity in the role of a buffer.

Many cells in the body need phosphorus for proper growth, repair, and better function, MSP can provide the phosphorus they need. The deficiency of this substance in the body can cause bone pain and Its high concentration causes kidney disorders.

Physical and chemical properties of Mono Sodium Phosphate MSP:

The IUPAC name of MSP is sodium dihydrogen phosphate, as mentioned, it can dissolve in water. disodium phosphate and trisodium phosphate are related chemicals.

Other cations include monopotassium phosphate and ammonium dihydrogen phosphate. This salt is not flammable. The most important physical and chemical properties can be summarized in the following table:

Heat and temperatures above 170 ° C can cause it to decompose and produce sodium pyrophosphate and water.

Synthesis and production of Monosodium Phosphate MSP:

Sodium phosphate can be produced during phosphoric acid neutralization operations. Sodium phosphate salts are generally produced by the reaction between phosphoric acid and sodium hydroxide. This mineral can be produced from the reaction of phosphoric acid and sodium chloride. Impurities must be separated into new production.

The combination of sodium carbonate and phosphoric acid can also lead to the production of two salts, MSP, and DSP.

This chemical composition is formed from the combination of these two salts at temperatures above 300 ° C.

Monosodium phosphate food grade:

• One of the special applications of MSP is in the food industry. The food-grade of MSP is added to animal feed and feed additives. it is also used in the production of toothpaste and milk, for example in the production of milk It is an emulsifier.

• Today, the use of this mineral in the production of various foods has greatly expanded. MSP plays a key role in food additives; this material can play the role of controlling and regulating acidity.
• Almost all sodium phosphates act as emulsifiers. Emulsifiers are used to uniformly disperse two or more substances that are otherwise unmixable. In food production, the most popular use for emulsifiers is to prevent oil from separating from the food product.
• The use of this mineral increases the shelf life of food and increases the quality and taste of food.
• This chemical composition is naturally present in many foods. The mineral phosphate is found naturally in milk, nuts, eggs.
• This important mineral is beneficial for bone health and a variety of kidney functions.

Safety information of Monosodium Phosphate MSP:

Observe the safety precautions when using it and avoid inhaling and direct contact with the skin and entering the eyes.

If the headache persists or you feel dizzy, go to medical centers. It is better to take a deep breath in the open air and inhale a little after inhaling it in high concentrations.

After direct contact with the skin, it is better to wash the area well with soap and water, and in case of inflammation or burning, and itching, go to medical centers. In case of contact with the eyes, wash it completely with soap and water.

Transporting and storage of Monosodium Phosphate MSP:

Store this material in a cool, dry place away from heat and sunlight.
