Diammonium citrate is a citrate salt in which two of the three carboxy groups are deprotonated and associated with ammonium ions as counter-cations. NB Price dependent on quantity ordered. [6] These are important effects in fighting wildfires as lowering the pyrolysis temperature and increasing the amount of char formed reduces that amount of available fuel and can lead to the formation of a firebreak. It’s water-soluble and dissolves rapidly in adequately moist soil. A nitrogen source commonly used to help promote yeast health. The exception is Malawi, where the planting fertilizers is a unique blend (23 N-21 P 2 O 5 -0 K and 4 S) especially imported by the government. DAP also acts as a fire retardant. (NH 4) 2 HPO 4 is also recognized but is too unstable for practical use. A notable property of DAP is the alkaline pH that develops around the dissolving granule.

It is also utilised as a fire retardant and as a nutrient for yeast in the winemaking process. In the cigarette industry, it finds application as a nicotine enhancer. The standard nutrient grade of DAP is relatively high, at 18-46-0, so fertilizer products with lower nutrient content may not be labeled DAP. Both triammonium salts evolve ammonia. When ammonia is added to phosphoric acid that hasn’t been heated, it produces monoammonium phosphate (11-52-0) or diammonium phosphate (18-46-0), depending on the ratio of the mixture. But in wine, DAP and similar products are used to prevent or fix fermentation problems. Cost and outcome. Diammonium Phosphate (DAP) is a good source of nitrogen for your yeast and will add nitrogen to keep the yeast active during fermentation. Brewers use Diammonium Phosphate (DAP) to increase the production and growth of … What is … [8][10], ammonium monohydrogen phosphate, ammonium hydrogen phosphate, ammonium phosphate dibasic, InChI=1S/2H3N.H3O4P/c;;1-5(2,3)4/h2*1H3;(H3,1,2,3,4), InChI=1/2H3N.H3O4P/c;;1-5(2,3)4/h2*1H3;(H3,1,2,3,4)/p-1, Except where otherwise noted, data are given for materials in their, "Nutrient Source Specifics: Diammonium Phosphate", "Effects of Ammonium Phosphate and Sulfate on the Pyrolysis and Combustion of Cellulose", Diammonium phosphate fertilizer manufacturing process flowsheet, https://en.wikipedia.org/w/index.php?title=Diammonium_phosphate&oldid=993961076, Articles with dead external links from September 2017, Articles with permanently dead external links, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Creative Commons Attribution-ShareAlike License, This page was last edited on 13 December 2020, at 12:19. Diammonium phosphate (DAP; IUPAC name diammonium hydrogen phosphate; chemical formula (NH4)2HPO4) is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid. At 155 °C (311 °F), DAP emits phosphorus oxides, nitrogen oxides and ammonia. § 573.320 Diammonium phosphate. The high nutrient content of DAP helps reduce handling, freight and application costs. following treatments should be considered for the specific group(s) of phosphate salts found in this product: --All phosphate salts, except calcium salts, have a hypothetical risk of hypocalcemia, so calcium levels should be 4. Diammonium phosphate (DAP) (chemical formula (NH4)2HPO4, IUPAC name diammonium hydrogen phosphate) is one of a series of water-soluble ammonium phosphate salts Benzer Multitech India Private Limited Bhosari, Pune S. No. (DAP) Diammonium phosphate (7783-28-0) LD50 oral rat 6500 mg/kg LD50 dermal rabbit > 7950 mg/kg Additional information This compound is listed by the FDA as generally recognized as safe (GRAS) and may be used as a food additive, for both human food and ruminant feed, according to … 7783 -28 -0 231-987-8 AGROPOLYCHIM JSCo We highly recommend using a scale to weigh the product for an accurate dose. Phosphoric acid and super phosphoric acid. [5] The typical formulation is 18-46-0 (18% N, 46% P2O5, 0% K2O). As dissolving DAP granules release ammonium, the seedlings and plant roots nearest the volatile ammonia can be harmed. When ammonia is added to phosphoric acid that hasn’t been heated, it produces monoammonium phosphate (11-52-0) or diammonium phosphate (18-46-0), depending on the ratio of the mixture. DAP fertilizer is an excellent source of P and nitrogen (N) for plant nutrition. A group MTDI of 70 mg/kg bw, as phosphorus from all food sources, was established at the 26th JECFA (1982) Pune, Maharashtra Diammonium phosphate (DAP; IUPAC name diammonium hydrogen phosphate; chemical formula (NH4)2HPO4) is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid. In 2017, diammonium phosphate agricultural use for Ethiopia was 121,086 tonnes. 2 & 4, Landge Nagar, Bhosari, Pune - 411039, Dist. Ammonium phosphate is a fast release fertilizer and can be used when planting new grass, for maintenance, when overseeding or when renovating the lawn. Phosphate treatments can reduce metal dissolution and transport from contaminated soils. There is a superior nutrient regimen (using Go-Ferm and Fermaid K) for wine making: It is the most widely used phosphate based fertiliser. Promotes yeast propagation. DAP is also commonly used to support cheese cultures, as a soil additive to increase pH levels in agriculture, to purify sugar and even control dyes in wool. Production Used to increase yeast production and growth. In 2017, diammonium phosphate agricultural use for Ethiopia was 121,086 tonnes. [4] When applied as plant food, it temporarily increases the soil pH, but over a long term the treated ground becomes more acidic than before upon nitrification of the ammonium. Cost and outcome. 3.
