Frequently Asked Questions
What are the main uses of Disodium Hydrogenphosphite?
Disodium dihydrophosphate, often referred to as its English Disodium Hydrogenphosphite. This agent has a wide range of uses and has its impact in both industrial and people's livelihood fields.
In the field of industry, it has an extraordinary effect in water treatment. It can be used as an auxiliary agent for water softening, and can reduce its concentration by complexing with metal ions such as calcium and magnesium in water to soften hard water. In this way, it reduces the loss of pipes and equipment due to scale accumulation and prolongs its service life. And when it is treated on the surface of metals, it is also very useful, which can help form a protective film to prevent metal rust, such as steel, aluminum and other metals. After treatment, corrosion resistance is greatly increased.
In the food industry, disodium dihydrophosphate is a commonly used quality improver. In baked goods, it can adjust the pH of the dough, optimize the yeast fermentation environment, and make bread and other products puff better and taste better. In meat products, it can increase its water retention, make the meat more tender and juicy, and help stabilize the color of the meat and keep its appearance attractive.
In the field of medicine, it can also be seen. In some pharmaceutical preparations, it acts as a buffer to maintain the acid-base balance of the pharmaceutical solution and ensure the stability and effectiveness of the drug. For example, some oral liquid preparations use it to adjust the pH value to prevent drug degradation and deterioration.
In agriculture, disodium dihydrophosphate can be added to compound fertilizers. Phosphorus is an essential nutrient for plant growth, which can promote root development and increase crop stress resistance, such as drought resistance and cold resistance. Although sodium is not a large demand for plants, it has a regulatory effect on some plant physiological processes. This agent can help plants efficiently absorb other nutrients and improve fertilizer utilization.
Chemical Properties of Disodium Hydrogenphosphite
Disodium dihydrophosphate, its chemical properties are quite important. This is a white crystalline powder that is easily soluble in water, and its aqueous solution is acidic.
When heated, disodium dihydrophosphate will lose water, and then convert into sodium pyrophosphate and other substances. When exposed to strong bases, it will react to form corresponding phosphates. For example, when reacted with sodium hydroxide, disodium hydrogen phosphate can be formed with water.
Because its aqueous solution is acidic, it has applications in many fields. In the food industry, it can be used as a food quality improver to adjust the pH of food, stabilize the structure of food, and in baked goods, it can adjust the pH of dough to make bread softer. In industry, it can be used as a water softener to remove calcium and magnesium ions from water, avoid scale formation, and can also be used in electroplating and other processes, playing a unique role.
Furthermore, disodium dihydrophosphate has certain stability, but under specific conditions, such as high temperature and high humidity, its chemical properties may change. Therefore, when storing and using, it is necessary to properly pay attention to environmental factors to avoid affecting its performance and quality.
Disodium Hydrogenphosphite in storage
When storing disodium hydrogen phosphate dihydrate, many things need to be paid attention to. This is the key to its quality and effectiveness.
First, moisture-proof is essential. This substance is hygroscopic. If exposed to humid air, it is easy to absorb moisture and deliquescent. Once deliquescent, it will not only change its shape, but also change from its original solid to wet mass, but also affect its chemical properties and purity. Therefore, it should be stored in a dry place and can be contained in a sealed container, such as a sealed glass bottle or plastic bucket, to prevent moisture from invading.
Second, the temperature also needs to be controlled. It should be placed in a cool environment to avoid high temperature. If the temperature is too high, it may cause its chemical changes, causing the active ingredients to decompose or deteriorate. Generally speaking, room temperature (about 15-25 degrees Celsius) is appropriate, and it must not be near fire sources or high-temperature equipment.
Third, it should not be ignored to avoid light. Although it is not extremely sensitive to light, long-term light, especially strong direct light, may have an adverse effect on its stability. Therefore, it should be stored in a dark place or stored in an opaque container.
Fourth, it should be stored separately from other chemicals. Due to its chemical properties, if it is co-stored with acids, bases or strong oxidants, or a chemical reaction occurs, it will cause danger or reduce quality.
Storage of disodium hydrogen phosphate dihydrate must beware of moisture, temperature control, protection from light and classified storage in order to ensure its stable quality and play its due role in application.
What is Disodium Hydrogenphosphite Production?
To obtain disodium hypophosphite, it is often followed in this way: yellow phosphorus is co-heated with lime milk and water to obtain a calcium hypophosphite solution. The reaction is as follows:
\ [4P + 3Ca (OH) _2 + 6H_2O = 3Ca (H_2PO_2) _2 + 2PH_3 ↑\]
After removing impurities, the calcium hypophosphite solution undergoes a metathesis reaction with the sodium carbonate solution.
\ [Ca (H_2PO_2) _2 + Na_2CO_3 = CaCO_3? + Na_2HPO_2\]
After the reaction is completed, the calcium carbonate precipitate is removed by filtration, and the filtrate is evaporated, concentrated, cooled and crystallized to obtain disodium hypophosphite crystals. After that, the finished product is obtained by centrifugation, drying and other processes.
Another method is prepared by reacting sodium hydroxide solution with hypophosphoric acid. Hypophosphoric acid is a monotonic medium-strong acid with strong reducing property. It reacts with sodium hydroxide:
\ [H_3PO_2 + NaOH = NaH_2PO_2 + H_2O\]
The amount of sodium hydroxide needs to be precisely controlled during the reaction, so that the two can be reacted according to the stoichiometric ratio to obtain disodium hydrogen hypophosphite. The reaction solution can be obtained through a series of operations such as impurity removal, concentration, crystallization, separation, drying, etc. The product obtained by this method has high purity, but the raw material cost is relatively high.
What are the environmental effects of Disodium Hydrogenphosphite?
The environmental impact of the phosphorite in the natural water body needs to be investigated in detail. If this substance enters the natural water body, it may cause water quality variation. Because of its phosphorus composition, or the risk of eutrophication of the water body. Plankton such as algae in the water, with phosphorus as an important nutrient, can be nourished or multiply rapidly. Algae blooms, which not only cause poor appearance of the water body, but also have different colors and flavors, and have a great impact on the dissolved oxygen in the water. Algae overpopulate, its respiration and decomposition process after death consume a lot of dissolved oxygen, causing the amount of dissolved oxygen in the water to decrease sharply, and aquatic organisms may die due to lack of oxygen, destroying the balance of water ecology.
As for the soil environment, if this substance enters the soil through rainfall runoff, it may change the physical and chemical properties of the soil. Or cause soil pH deviation, affecting the community structure and activity of soil microorganisms. Microorganisms are crucial in soil nutrient cycling, organic matter decomposition and other processes, and if they are disturbed, soil fertility may also be affected. Plant growth depends on soil fertility. Fertility changes, plant growth and development or are blocked, affecting the health and distribution of vegetation.
In terms of atmospheric environment, although disodium hydrogen phosphite is not a common gaseous pollutant, its production and use process, if not handled properly, the powder substance escapes into the atmosphere, or is one of the inhalable particulate matter, which affects air quality and poses a potential threat to human respiratory health. Overall, disodium phosphite has a significant impact on the environment, and its use and disposal should be treated with caution to ensure the safety of the ecological environment.
