実験手順

In an alternative reaction, the solid monocalcium phosphate is reacted with potassium sulfate to yield primarily KH2PO4 with little or no H3PO4 coproduct. Conversely, if a portion of the (uncrystallized) MCP/H3PO4 liquor is reacted with potassium sulfate the resulting KH2PO4 /H3PO4 solution will have a plant food value of 0-24-6. A portion of any of the K2O products may be recycled back to the acidulation vessel to provide makeup for the K2O lost in the hydrolysis sector.
