Diammonium Phosphate (DAP) for winery/making wine/brewery.Product Name: Diammonium Phosphate Other Name: Dibasic ammonium phosphate, diammonium phosphate; INS No. 342(ii),  Ammonii phosphas; Diammonium hydrogen phosphate, diammonium hydrogen tetraoxophosphate, diammonium hydrogen orthophosphate Assay: Not less than 96.0% and not more than 102.0% Molecular Formula: (NH4)2HPO4 Molecular Weight: 132.06 CAS Number: 7783-28-0 HS CODE: 3105300090   Properties: Colorless, monoclinic crystals. This salt slowly loses small quantities of ammonia in air. Density is 1.619, melting point is 155℃, soluble in water easily.   Application: Fertilizer, Feed additives, Flame retardants, Fire Extinguishing Agent, woods, paper.  For food grade, it is mainly used as ferment agent, nourishment, Acidity regulator, dough conditioner, raising agent, yeast food Functional uses: Acidity regulator, dough conditioner, raising agent, yeast food   Use 1: This product is used as a fermentation activator and is reserved for fermentation operations. It makes available ammonium ions, which can be directly assimilated by the yeast. Excess phosphates can lead to iron breakdown. Statutory provisions limit the amount of ammonium that can be   Use 2: DAP is used as a fertilizer. 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. It is incompatible with alkaline chemicals because its ammonium ion is more likely to convert to ammonia in a high-pH environment. The average pH in solution is 7.5–8. The typical formulation is 18-46-0 (18% N, 46% P2O5, 0% K2O).   DAP can be used as a fire retardant. It lowers the combustion temperature of the material, decreases maximum weight loss rates, and causes an increase in the production of residue or char. 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 is the largest component of some popular commercial firefighting products.   DAP is also used as a yeast nutrient in winemaking and mead brewing; as an additive in some brands of cigarettes purportedly as enhancer; to prevent afterglow in matches, in purifying sugar; as a flux for soldering tin, copper, zinc and brass; and to control precipitation of alkali-soluble and acid-insoluble colloidal dyes on wool.  Specification:   NO.
