Abstract

PROCEDURE FOR OBTAINING CRISTSALES DE TRISODICO FOSFATO. IT CONSISTS TO MAINTAIN IN THE BREAST OF THE TRISODIC PHOSPHATE SOLUTIONS TO CRYSTALLIZE A MOLAR NA20/P2O5 RATIO BETWEEN 3.5 AND 4, WITH A CONCENTRATION OF 6 TO 10 PER100 BY WEIGHT OF P2O5. FOR THIS IT IS BASED ON PHOSPHORIC ACID COMING FROM VIA HUMEDA AND IS NETRALIZED UP TO A PH BETWEEN 4.5 AND 9 AT A TEMPERATURE OF 80 C., IT IS FILTERED AND TAKES THE FILTERED SOLUTION OF ORTHOPHOSPHATES, WHERE BY SOSA CAUSTIC ACTION THE PH IS RAISED TO 12, PROCEEDING TO ADJUST THE MOLAR NA2O/P2O5 RATIO TO A VALUE BETWEEN 3.5 AND 4; THEN GOES TO THE FINAL CRYSTALLIZATION REACTOR, WHERE WITH REFRIGERATION AT TEMPERATURE BETWEEN 18 AND 26 C. SEPARATION OF THE TRISODIC PHOSPHATE CRYSTALS. (Machine-translation by Google Translate, not legally binding)
