7722-76-1 Usage

Chemical Properties

Ammonium phosphate occurs in two forms-the monobasic, NH4H2P04, and dibasic,(NH4)2HP04, forms, It is a white crystalline solid that is soluble in water. Ammonium phosphate is a product of the reaction between ammonia and phosphoric acid.Ammonium phosphate is an important fertilizer and is used as a fire retardant

Uses

Used as buffer solutions.

Toxicity

ADI: 0 to 70 mg/kg (amount of total phosphate as phosphorus; FAO/WHO, 2001).
GRAS (FDA, § 184.1141a, 2000).

Uses

As baking powder with sodium bicarbonate; in fermentations (yeast cultures, etc.); fireproofing of paper, wood, fiberboard, etc.

Chemical properties

colorless transparent tetragonal crystal. soluble in water, slightly soluble in alcohol, insoluble in acetone.

description

Ammonium dihydrogen phosphate (ADP) is a transparent, piezoelectric crystal containing no water of crystallization. Single crystals of this material were originally developed for use in underwater sound projectors and hydrophones. Transducer problems during World War II fostered a joint study program on this material by Bell Telephone Laboratories, Brush Development Company and the Naval Research Laboratories. An adequate and relatively simple technology was developed in this joint effect to grow ADP crystals and to fabricate them into sonar transducers. ADP is comparable to ordinary table salt in workability, brittleness and solubility. Blumenthal was one of the first investigators to demonstrate the successful microwave modulation of light by using the electrooptic effect in ADP.

Solubility in water(g/100ml)

Dissolving grams per 100 ml of water at different temperatures (° C):
22.7 g/0 ° C; 39.5 g/10 ° C; 37.4 g/20 ° C; 46.4 g/30 ° C; 56.7 g /40 ° C; 82.5 g/60 ° C; 118 g/80 ° C; 173 g/100 ° C

Definition

ChEBI: The ammonium salt of phosphoric acid (molar ratio 1:1).

Content analysis

Accurately weighed about 500mg sample, dissolved in 50ml of water, with 0.1mol/L sodium hydroxide titration to pH 8.0. per mL, 0.1mol/L sodium hydroxide is equivalent to diammonium phosphate [NH4H2PO4] 11.50 mg.

Purification Methods

Crystallise it from water (0.7mL/g) between 100o and 0o.

Preparation method

Venturi loop reaction method: 85% thermal phosphoric acid will be diluted 1.3 to 1.4 times, after the measurement into the venturi tube flow mixing reactor, where it is sufficiently homogeneously mixed and reacted with the incoming ammonia gas, and the reaction process is continued in the pipeline. Finally the qualified liquid enters into the cycle reaction tank, adjusting the Ph value between the range 4.4 to 4.6, filtering and cooling the filtrate down to 26 oC, obtaining the crystal solid, separating and dehydrating, and then drying it to obtain the dihydrogen phosphate Ammonium products.
H3PO4 + NH3 → NH4H2PO4
Neutralization method: firstly dilute the phosphoric acid to get a solution with 50% to 55% concentration, and then take some measured solution into an enamel reaction tank with stirring and jacket. In stirring, the ammonia gas is slowly added into the ammonia tube distributor for neutralization. Waiting till the Ph value of the neutralized solution gets between 4.2~4.6, filter it immediately and send it into the cooling crystallization mold, then obtain crystallization when the temperature gets down to 26 °. Dry after dehydration and then obtain ammonium dihydrogen phosphate products.
 H3PO4 + NH3 → NH4H2PO4
Mother liquor from separator is added into the iron remover with ammonium sulfide for removing iron, filtering, and then senting to the acid tank to adjust the acidity to Ph4.4~4.6. Refined mother liquor is supplied for recycling.
Metathesis method Calcium dihydrogen phosphate and ammonium sulfate were melted at 85-90 °C to produce a clear solution below the saturation concentration. Firstly, the calcium dihydrogen phosphate solution is added into the reactor, and the temperature of the steam is raised to 95 oC under stirring, and the ammonium sulphate solution is added slowly for metathesis reaction to produce ammonium dihydrogen phosphate and calcium sulphate. The end point of the reaction is that Ph value is about 4.4 to 4.6. After filtration, the filtrate is sent into the evaporator to the boiling point of 108 °C, and then is sended into the cooling crystallizer, cooling to 40 °C for crystallization, centrifugal separating, drying, and then obtaining ammonium dihydrogen phosphate product.
Ca (H2PO4) 2 H2O + (NH4) 2SO4 → This product + CaSO4 + H2O
The separated calcium sulfate is filtered and washed to produce a by-product. The lotion is returned for the feed.
