| titleOfInvention | Detergent sequestration compositions containing stp and nta |
| abstract | A SEQUESTRATION COMPOSITION HAVING A MOLAR RATIO OF ALKALI METAL NITRILOTRIACETATE TO ALKALI METAL TRIPOLYPHOSPHATE OF FROM ABOUT 1:13 TO ABOUT 2.2:1 AND HAVING A BULK DENSITY BELOW ABOUT 0.6 GRAM PER CC. AND BEING SUBSTANTIALLY FREE OF A STRING BASE; SAID SALTS BEING AT LEAST ABOUT 95% BY WEIGHT OF THE TOTAL COMPOSITION ON AN ANHYDROUS BASIS AND THE PROCESS FOR PRODUCING SEQUESTRATION COMPOSITIONS CONTAINING SAID SALTS UTILIZING ALKALI METAL TRIMETAPHOSPHATE AS ONE OF THE RAW MATERIALS. THE PROCESS COMPRISES (A) PREPARING A MIXTURE CONSISTING ESSENTIALLY OF AT LEAST ABOUT 13% BY WEIGHT OF WATER, FROM ABOUT 5% TO 60% BY WEIGHT OF ALKALI METAL NITRILOTRIACETATE AND AN AMOUNT OF ALKALI METAL BASE; THE MOLAR RATION OF SAID BASE TO SAID TRIACETATE BEING FROM ABOUT 1.1:1 TO ABOUT 26:1, (B) ADDING TO SAID MIXTURE AN AMOUNT OF ALKALI METAL TRIMETHAPHOSPHATE SUFFICIENT TO AT LEAST REACT WITH THE BASE AND A PORTION OF THE WATER AND (C) DRYING THE RESULTING COMPOSITION TO PRODUCE A DETERGENT PRODUCT WHICH IS SUBSTANTIALLY FREE OF SAID BASE AND WHICH CONTAINS ALKALI METAL NITRILOTRIACETATE AND ALKALI META TRIPOLYPHOSPHATE IN THE FOREGOING MOLAR RATIOS. |
