摘要： Disclosed is a method of making potassium tripolyphosphate by loading an ion exchange resin with either potassium or hydrogen ions and passing an aqueous solution of sodium tripolyphosphate through the resin so that the sodium ions of the sodium tripolyphosphate are exchanged with the ions loaded onto the resin, forming either potassium tripolyphosphate or tripolyphosphoric acid, respectively. The tripolyphosphoric acid is reacted with potassium hydroxide to form potassium tripolyphosphate. When the ion exchange resin becomes exhausted it is regenerated using a potassium-containing ionic solution, forming a sodium ion containing stream. The sodium ion containing stream is reacted with a phosphoric acid to form a stream of sodium phosphates.

摘要： Disclosed is a method of preventing fluids in the ground from rising around an oil well pipe by filling the space around the pipe with an oil well completion fluid comprising water, about 50 to about 65% by weight, based on total fluid weight, of dipotassium phosphate, and at least about 10 ppm hexavalent chromium. The fluid can be prepared by neutralizing wet process phosphoric acid with potassium hydroxide to a pH of less than 12 and filtering off any solids. Also disclosed is an oil well employing the completion fluid.

摘要： Disclosed is a method of making a eutectic mixture of copper and tricopper phosphide by reacting elemental copper with phosphine. The elemental copper is heated to a temperature above about 714.degree. C. and the liquid eutectic mixture runs off of the cooper as it is formed, exposing more copper for reaction. The liquid eutectic mixture can be used as a source of copper and phosphorus in making metal alloys.
