Na2HPO4+NaOH¡úNa3PO4+H2O
1. A process for the production of trisodium phosphate dodecahydrate Na3 PO4. 12H2 O. 1/4NaOH which comprises
2. preparing a solution of trisodium phosphate having a molar ratio of sodium to phosphorus of about 3.25:1,
3. adding to said solution an amount of sodium sulfate in the range of 0.2 to 0.8 percent, by weight of dry trisodium phosphate salt therein,
4. evaporating said solution to cocrystallize said trisodium phosphate dodecahydrate with said sodium sulfate from said solution thereby to produce a trisodium phosphate dodecahydrate having the characteristic that it is stable in storage under ordinary variations of humidity and temperature without ***erioration of the crystal and without the formation of agglomerated particles or cakes.
5. A process in accordance with claim 1, wherein the amount of sodium sulfate added is 0.30 percent of the trisodium phosphate dodecahydrate crystals.
6. A process in accordance with claim 1, wherein evaporation is carried out in continuous fashion, such that product is produced at a temperature between 40¡ã a |
