Potassium Dihydrogen Phosphate Powder Usage and Synthesis.

1、Promote nitrogen and phosphorus absorption. Potassium dihydrogen phosphate can promote the crop's absorption of nitrogen and phosphorus, quickly replenish the phosphorus, improve the crop yield and thousand grain weight, and can play a special role in the special physiological period of the crop.

2、Promote photosynthesis. Potassium plays a special role in crop growth to enhance photosynthesis and accelerate nutrient production and transformation.

3、Improve crop resistance. Potassium phosphate can improve crop resistance, such as drought resistance, resistance to hot and dry winds, resistance to flooding, resistance to freezing, resistance to damage to promote healing, resistance to disease infestation and so on.

4、Improve fruit quality. Fruit expansion period spraying can play a fruit protection and fruit, promote fruit expansion, can improve the quality of fruit, increase coloring, improve taste and so on.

5、Regulate the balanced growth of crops. Potassium dihydrogen phosphate has the role of regulator, can promote the crop bud differentiation, increase the number of flowers, buds strong, strong flowers to protect the fruit, improve fruiting, but also can effectively promote the growth and development of the root system.

Uses and functions of Potassium Dihydrogen Phosphate.

Preparation of buffer solution, determination of arsenic, antimony, phosphorus, aluminum and iron, preparation of phosphorus standard solution, preparation of various media for haploid breeding, determination of inorganic phosphorus in serum, alkaline acid enzyme activity, preparation of bacterial serum test for leptospirosis media, etc.

It is used as high-efficiency phosphorus and potassium compound fertilizer for various soils and crops. It is also used as bacterial culture agent, flavoring agent of synthetic sake, and raw material of potassium metaphosphate. In medicine, it is used to acidify urine and as a nutrient.

It is also used as a nutrient. It is also used as a texture improver to increase the complexation of metal ions, pH value and ionic strength of foodstuffs, thus improving the adhesion and water-holding capacity of foodstuffs. China's regulations can be used in wheat flour, the maximum use of 5.0g/kg; in the beverage maximum use of 2.0g/kg.

It is used as fertilizer, flavoring agent, brewing yeast culture agent, for the preparation of buffer solution, also used in medicine and the manufacture of potassium metaphosphate.

Preparation of Potassium Dihydrogen Phosphate.

Product method of Bulk Potassium Dihydrogen Phosphate Powder.

Phosphoric acid decomposition method at 120 ~ 130 ℃ with saturated potassium chloride solution and excess of 75% of phosphoric acid decomposition reaction, hydrogen chloride gas produced by water absorption by-products of hydrochloric acid; and then use potassium hydroxide to neutralize the excess of phosphoric acid, control the end point of the Ph value of 4.2 ~ 4.6; and finally cooling and cleaning, centrifugal separation, drying of the product, the mother liquor can also be reused.

Neutralization method under constant stirring, the caustic potash will be formulated into a relative density of 1.3 (about 30%) of the solution and 50% of the phosphoric acid neutralization; reaction temperature is maintained at 85-100 ℃, the end point of the control of the Ph value of 4.2 ~ 4.6 (Congo red paper was light purple); neutralization of the liquid concentration to a relative density of 1.32 ~ 1.33 after filtration, and then cooled to 36 ℃: the following crystallization, centrifugal separation, drying to get The mother liquor can also be reused. Can also be neutralized with potassium carbonate, process similar to the above.
