ERSCHEINUNGSBILD
GERUCHLOSE WEISSE KRISTALLE ODER PULVER.CHEMISCHE GEFAHREN
Zersetzung beim Erhitzen über 100°C oder bei Kontakt mit starken Basen unter Bildung giftiger und ?tzender Rauche mit Ammoniak, Stickstoffoxiden und Phosphoroxiden. Schwache Base in w?ssriger L?sung. Reagiert heftig mit starken S?uren und starken Oxidationsmitteln. An der Luft allm?hliche Freisetzung von Ammoniak.ARBEITSPLATZGRENZWERTE
TLV nicht festgelegt (ACGIH 2005).MAK nicht festgelegt (DFG 2005).
AUFNAHMEWEGE
Aufnahme in den K?rper durch Inhalation des Aerosols.INHALATIONSGEFAHREN
Verdampfen bei 20°C vernachl?ssigbar; eine bel?stigende Partikelkonzentration in der Luft kann jedoch beim Dispergieren schnell erreicht werden, vor allem als Pulver.WIRKUNGEN BEI KURZZEITEXPOSITION
WIRKUNGEN BEI KURZZEITEXPOSITION:Die Substanz reizt die Augen.
LECKAGE
Verschüttetes Material in abgedeckten Beh?ltern sammeln; falls erforderlich durch Anfeuchten Staubentwicklung verhindern. Reste mit viel Wasser wegspülen. Pers?nliche Schutzausrüstung: Atemschutzger?t, P2-Filter für sch?dliche Partikel.R-S?tze Betriebsanweisung:
R36/37/38:Reizt die Augen, die Atmungsorgane und die Haut.R20/21/22:Gesundheitssch?dlich beim Einatmen,Verschlucken und Berührung mit der Haut.
S-S?tze Betriebsanweisung:
S26:Bei Berührung mit den Augen sofort gründlich mit Wasser abspülen und Arzt konsultieren.S36:DE: Bei der Arbeit geeignete Schutzkleidung tragen.
Beschreibung
Ammonium phosphates include mono- and diammonium orthophosphates and ammonium polyphosphates. As discussed below, these are made directly by reaction anhydrous ammonia with orthophosphoric acid or superphosphoric acid. Both are dry crystalline materials with good handling properties.Chemische Eigenschaften
white crystalline powderPhysikalische Eigenschaften
Colorless monoclinic crystal; saline taste; refractive index 1.52; density 1.619 g/cm3; melts at 155°C (decomposes); very soluble in water (57 g/100 g at 10°C and 106.7g/100g at 70°C, respectively); insoluble in alcohol, acetone, and liquid ammonia.Verwenden
Ammonium Phosphate Dibasic is a general purpose food additive that is readily soluble in water, with approximately 57 g dissolving in 100 g of water at 0°c. a 1% solution has a ph of 7.6–8.2. it is used as a dough strengthener, firming agent, leavening agent, and ph control agent. its uses include baked goods, alcoholic beverages, condiments, and puddings. in bakery products, up to 0.25 part per 100 parts by weight of flour is used.synthetische
(NH4)2HPO4 is made by reacting ammonia with phosphoric acid:2NH3 + H3PO4 → (NH4)2HPO4.
Definition
ChEBI: An inorganic phosphate, being the diammonium salt of phosphoric acid.Landwirtschaftliche Anwendung
With excess ammonia, the technical grade of diammonium phosphate (DAP) contains 16 to 18% nitrogen and 20to 21 % phosphorus.DAP is an important fertilizer as well as an intermediate in the production of complex fertilizers and bulk blends.
Kontakt-Allergie
A flame retardant caused contact dermatitis in surgical personnel. It was due to excessive residual concentrations in surgical garbs.Sicherheitsprofil
Low to moderate toxicity. See also PHOSPHATES. When heated to decomposition it emits very toxic fumes of POx, NOx, and NH3.m?gliche Exposition
Used in fireproofing of textiles; wood and paper; in soldering flux; as a fertilizer; a buffer; in baking powder and food additives.Versand/Shipping
There are no DOT/UN listed requirements.l?uterung methode
Crystallise it from water (1mL/g) between 70o and 0o. Its solubility in H2O is 59% at room temperature and 200% at the boiling point. It slowly evolves NH3 and should be stored in a well-stoppered container. After one crystallisation, ACS grade salt had Fe, Mo, Na, Se and Ti at 1, 0.2, 1.4, 0.2 and 0.8ppm, respectively. [Gmelin’s, Ammonium (8th edn) 23 pp422-426 1936.]Inkompatibilit?ten
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Contact with air causes this chemical to produce anhydrous ammonia fumes.Waste disposal
May be flushed to sewer with huge volumes of water.Diammoniumhydrogenorthophosphat Upstream-Materialien And Downstream Produkte
