How is Dipotassium Phosphate Anhydrous DKP-A made?
It is usually made by neutralizing phosphoric acid and potassium hydroxide. First, put phosphoric acid in an enameled reactor, slowly add potassium hydroxide, and stir while adding. At this time, hot air will be generated in the reactor and the solution will gradually thicken. It is necessary to check with test paper from time to time. When the pH value reaches about 8, stop adding materials and continue stirring for half a day to make the reaction thorough. Then transfer the solution to an evaporating dish and heat it over a low fire to gradually remove the water. When it is thick like slurry, transfer it to a crystallization tank and let it stand overnight, and crystals will precipitate. Then place the crystals in a drying oven and dry them at 60 degrees Celsius to remove all the water, and you will get anhydrous Dipotassium Phosphate Anhydrous DKP-A. The method is like mixing soup with a spoon. The proportion is appropriate and the taste is pure. This also requires accurate ingredients. One more point will be too alkaline, and one less point will be too acidic. Both are unusable, so it requires careful control by craftsmen.
What is the appearance of Dipotassium Phosphate Anhydrous DKP-A?
It is white powder or granules. The granules are like fine sand and are uniform in size. The powder is like flour and is fine and has no residue. It is odorless and tasteless. It looks crystal clear. The pure ones have no impurities. It is very soluble in water and dissolves very quickly. The aqueous solution is weakly alkaline with a pH value of about 9. Because it is anhydrous, its hygroscopicity is slightly slower than that of aquatic products. However, if it is placed in a humid place, it will clump slightly after ten or six months. It has a delicate touch. When scattered, it is like fine sand flowing. It feels greasy when twisted. It does not react with most organic matter, but it will produce bubbles and release heat when it meets acid. It is stable at high temperatures and will not decompose until heated to above 200 degrees Celsius. Therefore, there is no need to worry about its property changes during cooking and industrial heating.
Where can Dipotassium Phosphate Anhydrous DKP-A be used?
It can be used in food, agriculture, and industry, each to its full potential. In the food industry, when used as an emulsifier, it can be added to dairy products to blend oil and water, making the dairy products delicate and smooth; when used as a nutritional enhancer, it can supplement phosphorus and potassium elements, added to beverages and cereals, and help the human body absorb nutrients. In agriculture, it can be used as a fertilizer to make foliar fertilizer or base fertilizer to supplement the phosphorus and potassium of plants, so that the root system of crops is developed and the fruits are plump, especially suitable for fruits, vegetables and other categories. In industry, it can be used as a water treatment agent to adjust the hardness of water and prevent scaling in pipes; in the pharmaceutical industry, it can be used as a buffer to adjust the pH value of the liquid medicine to stabilize the efficacy. In addition, in cosmetics, it can be used as a moisturizer to make the cream delicate and easy to apply. Its use is like a good craftsman's tool, changing according to needs, and it can do its best, so it is favored by many industries.
What rules should be followed when storing Dipotassium Phosphate Anhydrous DKP-A?
It should be stored in sealed bags or cans. Thick plastic bags need to be double-wrapped and the bag mouth should be tied tightly. Ceramic cans need to be covered with rubber plugs to prevent moisture from entering. The place to place should be a dry and ventilated room with a temperature of 15 to 25 degrees Celsius. Avoid direct sunlight and high temperature places, such as stoves and heaters. If it absorbs moisture, it is easy to clump. Although the medicinal effect is not reduced after grinding, it is difficult to use and the purity is slightly reduced. When stacking, it needs to be one foot off the ground, with wooden boards and oil paper underneath to prevent the ground from getting wet; half a foot away from the wall to prevent moisture from penetrating the wall. If long-distance transportation is required, a sealed wooden box should be used with moisture-proof paper inside. It needs to be covered with oilcloth in rainy days and should not be exposed to rain. The ancients said, "When the granaries are full, the world is at peace." The storage of this product also needs to be dry in the granary to preserve its quality for a long time, and its effectiveness will remain the same after seasons and years.
What is the difference between Dipotassium Phosphate Anhydrous DKP-A and the water-containing product?
The most obvious difference is the water content. This anhydrous product has no crystal water, so its molecular structure is tight, the weight is lighter, and the content is higher under the same volume. Because it is water-free, it is easier to dissolve. It will dissolve in water in a moment, and the concentration of the aqueous solution is also high; while the water-containing product contains crystal water, so the dissolution rate is slightly slower and the concentration is also slightly lower. In terms of hygroscopicity, the water-free product is slower. If placed in a dry place, it will not clump for more than a month; the water-containing product absorbs moisture faster and may clump in ten days. In terms of use, the water-free product is more suitable for scenes that require strict control of moisture, such as powdered food and fine chemicals; the water-containing product is mostly used in liquid products, such as beverages and pharmaceuticals. During storage and transportation, the water-free product is more resistant to moisture, and the water-containing product requires more stringent moisture-proof measures. The two are like the dry and wet states of the same thing, with the same origin, but slightly different properties and uses. Users should choose according to their needs.
