| titleOfInvention | IMPROVEMENTS INTRODUCED IN PROCEDURES FOR OBTAINING CRYSTALS OF TRISODIC PHOSPHATE |
| abstract | PROCEDURE FOR OBTAINING TRISODIUM PHOSPHATE CRISTSALS. IT CONSISTS OF KEEPING A MOLAR RATIO NA20 / P2O5 BETWEEN 3.5 AND 4 IN THE SINUS OF TRISODIUM PHOSPHATE SOLUTIONS TO CRYSTALIZE, WITH A CONCENTRATION OF 6 TO 10 PER 100 IN WEIGHT OF P2O5. TO DO THIS, IT IS STARTED FROM PHOSPHORIC ACID FROM THE WET WAY AND IS NETRALIZED UP TO A PH BETWEEN 4.5 AND 9 AT A TEMPERATURE OF 80 C., THE FILTERED SOLUTION OF ORTHOPHOSPHATES IS TAKEN TO A REAXCATOR, WHERE BY ACTION OF SOSA CAUSTIC THE PH IS RAISED TO 12, ADJUSTING THE MOLAR RATIO NA2O / P2O5 TO A VALUE BETWEEN 3.5 AND 4; THEN IT GOES TO THE FINAL CRYSTALIZATION REACTOR, WHERE WITH REFRIGERATION AT A TEMPERATURE BETWEEN 18 AND 26 C. THE CRYSTALS OF TRISODIUM PHOSPHATE ARE SEPARATED. |
