What raw materials are used to make Monopotassium Phosphate MKP?
This product is mostly made of phosphoric acid and potassium hydroxide as raw materials, and is made through a neutralization reaction. Put phosphoric acid in a stone reaction tank, scoop potassium hydroxide powder with a copper spoon, and slowly sprinkle it in, stirring it with a wooden paddle while sprinkling. The solution will boil slightly at first. When the temperature drops to about 40 degrees and the pH value is about 4.5, stop stirring. Continue stirring for an hour to make the reaction thoroughly, move it into a ceramic plate to evaporate until a crystal film precipitates on the surface, let it stand and cool, and needle-shaped crystals will form. After filtering out and drying in the sun, Monopotassium Phosphate MKP is obtained. The method is similar to boiling a paste. If there are too many materials, the alkali is heavy, and if there are too few, the acid is left. Only those that are in the middle are pure products.
What is the shape and properties of Monopotassium Phosphate MKP?
It mostly appears as white crystals, shaped like fine needles or columns, and when gathered together, it looks like a pile of snow, with a bright and shiny luster. It is brittle and easy to grind, and it is smooth when twisted, and there is no sound when it is scattered. It is soluble in water, and its aqueous solution is acidic with a pH value of about 4.2. It can combine with calcium and magnesium ions. It has weak hygroscopicity and will not clump when placed in a dry place for more than a season. However, it will also deliquesce if stored in a wetland for a long time. It releases heat when it meets a strong alkali, so it cannot be stored with caustic soda. It is stable at high temperatures and will not decompose until it is burned to 2,000 degrees, so it does not need to be stored away from fire sources. Its crystals have good light transmittance and are still white and free of impurities after being ground into powder.
Where can Monopotassium Phosphate MKP be applied?
In agriculture, it is the best choice for foliar fertilizer. It contains phosphorus and potassium. Spraying it on fruit trees and vegetables can promote fruit enlargement and increase sweetness. Applying it to flowers can make the flowers colorful and prolong the flowering period. In industry, it is an essential buffer, used in electroplating liquid to adjust the pH and make the coating uniform. In cosmetics, it can be used as a moisturizer to make creams delicate and easy to apply. In the food industry, it can be added to beverages as a nutritional enhancer to supplement the body's phosphorus and potassium; in the fermentation industry, it is a source of nutrition for microorganisms and helps them reproduce. Its use is like a skilled craftsman's chisel, carving according to the object, and it can show its function.
How should Monopotassium Phosphate MKP be stored?
It should be placed in glass bottles or ceramic jars, sealed with rubber stoppers, and placed in wooden boxes with moisture-proof paper inside. Store in a dry and ventilated room with a temperature of 15 to 25 degrees, two feet from the ground and one foot from the wall. If the quantity is large, it can be packaged in thick plastic bags, 30 kilograms per bag, and the bag mouth is tightly tied and covered with a wooden box. The box needs to be opened and inspected during the rainy season. If it is slightly damp, replace the moisture-proof paper. Choose a sunny day for transportation to avoid rain. If it rains, cover it with oilcloth. The key to storage is to prevent moisture and moisture, and long-term storage will not damage its properties.
What is the difference between Monopotassium Phosphate MKP and Dipotassium Phosphate?
Although both contain potassium and phosphorus, the potassium content and pH value are different. Monopotassium Phosphate MKP contains less potassium and its aqueous solution is acidic; Dipotassium Phosphate contains more potassium and its aqueous solution is weakly alkaline. In terms of usage, the former is suitable for foliar fertilizer and buffer, while the latter is more suitable for food emulsification and water treatment. The production methods are also different. The former reacts phosphoric acid with potassium hydroxide to acidity, while the latter to weak alkalinity. Like two ministers, civil and military, they both assist the same master, but their duties are different, and users should distinguish their properties.
