Phosphate → Monobasic potassium phosphate

Participants

Reaction Steps

The fine particles of potassium chloride or sodium chloride and the fine particles of phosphate or a buffering agent may be separately prepared. For example, when a concentrated aqueous solution of potassium chloride or sodium chloride is formed, an aqueous solution of potassium dihydrogen phosphate and sodium dihydrogen phosphate (4:6 in molar ratio) can be separately formed. Both solutions are preferably in a saturation state, which provides a greater amount of fine particles, i.e., a high efficiency. Note that the weighed phosphates must be completely dissolved in water, because the proportion of the dissolved phosphates significantly affects the pH value. The thus-prepared aqueous solutions are poured into an organic solvent such as ethanol, in the same manner as described above, respectively, and the precipitated fine particles are collected.
