| titleOfInvention | A kind of method preparing sodium dihydrogen phosphate by-product Semen Fagopyri Esculenti special fertilizer |
| abstract | The present invention relates to chemical technology field, disclose a kind of method preparing sodium dihydrogen phosphate by-product Semen Fagopyri Esculenti special fertilizer, the method is the amount by the various nutrients absorbed from soil in detection Semen Fagopyri Esculenti growth course, then the ratio of the nutrient needed for the growth of analysis Semen Fagopyri Esculenti, phosphoric acid and phosphoamide is used to react generation intermediate, react with alkaline sodium salt with this intermediate again, by the strict parameter controlled in reaction, make a part of sodium dihydrogen phosphate crystallization that reaction generates, nitrogen in regulation reactant liquor, it is required that the content of phosphorus meets Semen Fagopyri Esculenti growth, and in reactant liquor add potassium and in other trace compound prepare Semen Fagopyri Esculenti special fertilizer.The method not only makes the sodium dihydrogen phosphate purity of preparation higher, but also by-product Semen Fagopyri Esculenti special fertilizer, make the raw material be fully utilized. |
