| titleOfInvention | A kind of production method preparing tricalcium phosphate by-product Fructus Mangifera Indicae special fertilizer |
| abstract | nullThe present invention relates to chemical technology field，Especially a kind of production method preparing tricalcium phosphate by-product Fructus Mangifera Indicae special fertilizer，By in the preparation technology to tricalcium phosphate product，Adopt phosphoric acid and urea reaction，And control temperature when reacting，Make the urea phosphate recurring structure conversion reaction generated，And then form the urea phosphate of ionic species，Again under the excessive premise of phosphoric acid，Phosphoric acid and cation react a kind of intermediate-ion body with complexing of formation and dihydrogen phosphate，And then addition calcium ion reacts production tricalcium phosphate，And according to the Fructus Mangifera Indicae demand to n-p-k element，Control to produce the nitrogen and phosphorus content of residual in the solution in tricalcium phosphate technique，Again through the mode adding potassium element，Adjust the ratio of n-p-k element，Comply with Growth of Mango demand，And then improve the purity of tricalcium phosphate product and reduce discharging of waste liquid amount，Reduce production cost. |
