What is Disodium Phosphate?

Disodium Phosphate, also known as Sodium Phosphate Dibasic or Di-Sodium Hydrogen Phosphate, is a colourless to white crystalline solid that is soluble in water. Na2HPO4 is the sodium salt of phosphoric acid and exists as a highly water-soluble and hygroscopic white powder. Di-Sodium Phosphate is produced by reacting a solution of phosphoric acid with caustic soda to achieve a higher pH. The compound is widely used in various industries and applications due to its solubility and chemical properties. In the manufacturing process, Di-Sodium Phosphate can be obtained through a series of reactions involving monosodium sulfate, phosphate rock, dicalcium phosphate, and phosphoric acid. The resulting filtrate undergoes neutralization stages with calcium carbonate or calcium hydroxide, followed by a second neutralization with an alkali sodium constituent such as sodium hydroxide, sodium carbonate, or sodium bicarbonate. This process ultimately yields pure Di-Sodium Phosphate through crystallization.

How to Make Disodium Phosphate?

The manufacturing process of disodium phosphate involves several steps. Here is a brief overview:

  1. Phosphoric Acid Production: Phosphoric acid is typically produced by treating phosphate rock with sulfuric acid. This reaction forms phosphoric acid and calcium sulfate, which is commonly known as gypsum.
  2. Reaction with Sodium Hydroxide: A solution of phosphoric acid is then reacted with sodium hydroxide (caustic soda). The reaction between phosphoric acid and sodium hydroxide produces disodium phosphate.
  3. pH Adjustment: During the reaction, the pH of the solution is carefully controlled and adjusted to the desired level. This is done by adding the appropriate amounts of phosphoric acid or sodium hydroxide to achieve the desired pH.
  4. Crystallization: The resulting solution containing disodium phosphate is subjected to a crystallization process. By carefully controlling the temperature and concentration, the disodium phosphate crystals are allowed to form and separate from the solution.
  5. Filtration and Drying: The disodium phosphate crystals are then separated from the remaining liquid through filtration. The crystals are washed to remove any impurities and then dried to obtain the final product, which is a white crystalline powder.
  6. Quality Control: The final product is tested to ensure it meets the required specifications and quality standards. This includes checking the purity, moisture content, and other relevant parameters.

It’s important to note that specific manufacturing processes may vary depending on factors such as the desired grade of disodium phosphate and the manufacturer’s techniques and equipment.

Is disodium phosphate an acid or base?

Disodium phosphate (Na2HPO4), also known as disodium hydrogen phosphate, is classified as a salt. It is derived from the reaction of phosphoric acid (a weak acid) with sodium hydroxide (a strong base). Therefore, disodium phosphate is considered to be a basic salt or a conjugate base. When dissolved in water, it can act as a weak base, as it can accept protons (H+) from water molecules to form hydroxide ions (OH-).

Is disodium phosphate an antioxidant?

Disodium phosphate (Na2HPO4) is not primarily classified as an antioxidant. It is a sodium salt derived from orthophosphoric acid and is commonly used in the food industry as a stabilizer, buffering agent, and sometimes as an antioxidant synergist.

As a stabilizer, disodium phosphate helps maintain the consistency, texture, and shelf life of various food products. It is often added to processed foods, such as canned goods, dairy products, and baked goods, to prevent undesirable changes in their physical properties over time.

Disodium phosphate also serves as a buffering agent, helping to regulate the pH levels in food and beverage formulations. By controlling the acidity or alkalinity of a product, it can enhance flavour, improve texture, and increase the effectiveness of other additives.

While disodium phosphate is not directly an antioxidant, it can act as an antioxidant synergist in some food applications. An antioxidant synergist works in conjunction with primary antioxidants to enhance their effectiveness in preventing oxidation, which can lead to the deterioration of food products. Disodium phosphate can help improve the overall antioxidant capacity of a food formulation by working synergistically with other antioxidants present.

Is disodium phosphate organic?

Disodium phosphate (DSP), also referred to as disodium hydrogen phosphate or sodium phosphate dibasic, is an inorganic compound that consists of sodium cations (Na+) and phosphate anions (HPO42-). Its chemical formula is Na2HPO4.
