화학적 성질
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 retardant물리적 성질

물리적 성질
White crystalline powder; odorless; density 1.80 g/cm3; readily dissolves in water (40 g/ 100 g); pH of 0.2 molar solution 4.2; slightly soluble in alcohol; insoluble in acetone.용도
Ammonium dihydrogen phosphate is a general purpose food additive which is readily soluble in water. A 1% solution has a ph of 4.3–5.0. It is used as a dough strengthener and leavening agent in baked goods and as a firming agent and ph control agent in condiments and puddings. It is also used in baking powder with sodium bicarbonate and as a yeast food.정의
ChEBI: The ammonium salt of phosphoric acid (molar ratio 1:1).제조 방법
Preparative method similar to its dibasic salt; obtained by reaction of equimolar amounts of ammonia and phosphoric acid:NH3 + H3PO4 → (NH4)H2PO4.
일반 설명
Ammonium phosphate monobasic (APM) is an inorganic salt widely used in fertilizer, baking powder and yeast production. It is also employed as an agent to control pH of a solution and in corrosion inhibition. APM can be prepared by reacting phosphoric acid with anhydrous ammonia maintaining the pH below 5.8. The change in some of the physical characteristics on its addition to a high carbonate containing unfired and fired illitic shale has been studied.농업용
Ammonium phosphates refer to a generic class of phosphorus fertilizers and are manufactured by reacting anhydrous ammonia with orthophosphoric acid or superphosphoric acid. These are either in solid or liquid form.Ammonium phosphate fertilizers are highly soluble in water and fast acting in soil to give nitrogen and phosphorus in a chemical combination. They form an important base for many compound fertilizers. Both mono and diammonium phosphates have good physical properties when synthesized from the wetprocess phosphoric acid. Storage properties and the ease of granulation depends on the amount of impurities, which form a gel like structure (mainly aluminum and iron phosphates). This gel promotes granulation and serves as a conditioner to prevent caking even at moderately high moisture levels. A small proportion of phosphate rock added to phosphoric acid before ammoniation improves the granulation.
Ammonium phosphates, particularly Ammonium dihydrogen phosphate(DAP), are the most popular phosphate fertilizers worldwide because of their high utility and good physical properties. The standard commodity grade of diammonium phosphate is 18-46-0. Pure and completely soluble ammonium phosphates are used mainly as liquid fertilizers. In Britain, diammonium phosphate is not sold directly in this form, but is used to make compound fertilizers with a wide variety of plant foods.
잠재적 노출
Used in fireproofing of textiles; wood and paper; in soldering flux; as a fertilizer; a buffer; in baking powder and food additives.운송 방법
There are no DOT/UN listed requirements.Purification Methods
Crystallise it from water (0.7mL/g) between 100o and 0o.비 호환성
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.폐기물 처리
May be flushed to sewer with huge volumes of water.제1인산암모늄 준비 용품 및 원자재
