Abstract

A METHOD FOR PRODUCING LONG-CHAIN CRYSTALLINE POTASSIUM AMMONIUM POLYPHOSPHATES WITH THE GENERAL FORMULA KX(NH4)YPNO2N+1 WHERE N IS GREATER THAN ABOUT 50, X+Y=N+2, AND Y/X RANGES FROM 0.25 TO 4.0 BY THERMAL CONDENSATION OF AMMONIUM ORTHO-, PYRO-, TRIPOLY-, TETRAPOLY, TETRAMETA-, OR LONG-CHAIN POLYPHOSPHATES WITH POTASSIUM ORTHOPHOSPHATE, METAPHOSPHATE, CARBONATE, OR CHLORIDE BY HEATING IN A STREAM OF AMMONIA AT TEMPERATURES OF ABOUT 200*C. TO 400*C. FOR A PERIOD OF ABOUT 1 TO 16 HOURS. THE STRONGEST LINES IN THE X-RAY POWER DIFFRACTION PATTERNS ARE GIVEN. THE PRODUCT MOLE RATIO K/N IS SUBSTANTIALLY THE SAME AS THE MOLE RATIO K/(P-K) IN THE STARTING MATERIAL, AND THE PRODUCTS ARE HIGH-ANALYSIS FERTILIZERS WITH N-P2O5-K2O GRADES RANGING FROM 262-33 TO 11-70-10. SMALL AMOUNTS. OF CU, ZN, B, FE, AND MO WERE INCORPORATED AS MICRONUTRIENTS IN SEVERAL PREPARATIONS.
