구연산 암모늄, 삼염기 C화학적 특성, 용도, 생산

화학적 성질

white crystalline powder

화학적 성질

Ammonium citrate (various forms) is a white powdery material with a slight ammonia-like odor.

용도

Ammonium citrate tribasic is mainly used for chemical analysis, in industry for water treatment, in food industry for buffering agent and emulsifier, for metal surface cleaning (in particular petroleum pipeline cleaning), as a ceramic dispersant,as auxiliary infiltration agent, as detergent material and as soil improvement agent component.Ammonium citrate tribasic is applied in electroplating industry for non cyanide plating complexing agent, used mostly for preparing anti rust agent in machinery industry and as buffering agent. It serves as a chemical reagent in analytical chemistry to determine the efficient phosphate levels in phosphate salts and fertilizer.

용도

Ammonium citrate tribasic is widely utilized as a buffering agent and emulsifier in food industry. It acts as a complexing agent in electroplating industry and is also used for metal surface cleaning. It is employed in chemical analysis and in water treatment. It serves as a chemical reagent in analytical chemistry to determine the efficient phosphate levels in phosphate salts and fertilizer. It is used in industries for water treatment, as a ceramic dispersant, a detergent material and a component for soil improvement. It is used in medical and electronics industries as an auxiliary infiltration agent.

정의

ChEBI: A citrate salt in which all three carboxy groups are deprotonated and associated with ammonium ions as counter-cations.

농업용

Ammonium citrate is a white, granular, water-soluble salt of ammonia and citric acid. It is used in a neutral solution for determining the phosphorus content of phosphate fertilizers (such as calcium hydrogen phosphate (CaHPO4)), that are insoluble in water but dissolve in complexing citrate solutions.
The fertilizer residue, after extraction of watersoluble phosphorus, is re-extracted with a neutral or strongly alkaline solution of 1 normal (1N) ammonium citrate for a prescribed period, and the slurry filtered. Citrate-soluble phosphorus is the phosphorus content in the filtrate and is expressed as a percentage by weight of the fertilizer.
The extraction of phosphate with 1N ammonium citrate is carried out routinely for 30 minutes, first at room temperature and then at 4O℃ For neutral ammonium citrate solution, a temperature of 65℃ is preferred.
Some European countries use an alkaline ammonium citrate solution, which extracts smaller amounts of phosphorus. Some experts consider it to be better correlated with phosphorus uptake and plant growth. However, most countries use a neutral normal ammonium citrate solution for extracting citrate soluble phosphorus.

잠재적 노출

It is used to make pharmaceuticals; rust-proofing compounds and plasticizers; as a food additive; stabilizing agent.

운송 방법

UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

비 호환성

Contact with strong caustics causes the release of ammonia gas.

폐기물 처리

May be flushed to sewer with large volumes of water.
