Abstract: There is disclosed a novel process for preparing hemipotassium phosphate useful as an acidulant for beverages. An equimolar mixture of monopotassium phosphate and phosphoric acid is heated to a temperature above 100.degree. C. cooled with vigorous agitation whereby the liquid loses its free water and crystallizes to a relatively dry crystalline mass. When prepared by the process of this invention hemipotassium phosphate provides a dry, flowable, crystalline product which can be transported and handled easily.

Abstract: A novel leavening composition containing hemipotassium phosphate in combination with a carbonate factor. The hemipotassium phosphate is prepared by solution crystallization with removal of water.

Abstract: There is disclosed a process for preparing sodium tripolyphosphate which will dissolve readily in an aqueous solution also containing sodium chloride and various spices and flavorings useful in the treatment of food products such as fresh red meats, poultry and fish. The sodium tripolyphosphate of this invention is prepared from a dry blend of disodium phosphate and monosodium phosphate in a weight ratio in the range of from about 2.35 to about 2.45. The dry blend is calcined so as to produce a product having from 85% to 90% sodium tripolyphosphate, of which from about 90% to 100%, by weight, is phase II product. The product also contains about 10% to about 15% sodium pyrophosphate.

Abstract: There is disclosed a caking inhibitor for mono-and diammonium phosphates which is water soluble and effective at small concentrations rendering the phosphates acceptable in most utilities without separation of the inhibitor. The inhibitor is sodium sulfate. Effective amounts of this salt range from about 0.5 percent to about 1 percent by weight in the ammonium phosphates. It is particularly advantageous that this salt is useful in both types of ammonium phosphates.

Abstract: There is disclosed a process for preparing mixed alkali metal salts of tripolyphosphate. A solution of mixed orthophosphate salts, such as sodium and potassium is dried by spraying the mixture onto a hot tumbling bed of a mixture of phosphate salts. The dried salts are then calcined at a temperature in the range of from about 350.degree. C. to about 600.degree. C., preferably above 500.degree. C. to form the mixed alkali metal salt of tripolyphosphate.

Abstract: A process for preparing high absorptivity granular sodium phosphate mixtures made of sodium tripolyphosphate, pyrophosphates, metaphosphates and orthophosphates by hydrating and dehydrating a mixture comprising sodium tripolyphosphate in major proportion, and recovering the high absorptivity granular sodium phosphate mixture.

Abstract: A method of producing medium density granular sodium tripolyphosphate by compacting sodium tripolyphosphate fines with dried sodium orthophosphate salt followed by calcining the compacted mixture at a temperature in the range of from about 300.degree. C. to about 600.degree. C.

Abstract: A method of producing medium density granular sodium phosphates by agglomerating STP fines with mineral acids, drying the agglomerated fines and screening to recover the dry agglomerated fines.

Abstract: There is disclosed a process from producing granular sodium tripolyphosphate of predetermined particle size by means of calcining sodium orthophosphate dried from water solution and milled to a predetermined particle size. The tripolyphosphate is produced having approximately the same particle size distribution as the orthophosphate feed. Moisturizing the feed prior to calcining increases the assay of the product.

Abstract: A process for maintaining live fish is disclosed wherein the live fish are confined within a dilute solution containing an alkali metal Kurrol's salt which is preferably potassium Kurrol's salt.

Abstract: A composition of matter in particulate, crystalline form. The composition comprises a hydrate-forming phosphate selected from the group consisting of sodium tripolyphosphate, sodium pyrophosphate and trisodium phosphate, between about 0.1% by weight and about 23% by weight added water in the form of water of hydration said water containing in solution sufficient surfactant to provide the composition from about 0.20 ppm and about 125 ppm of a surfactant. Methods for preparing such compositions are also disclosed.
