Description
Ammonium citrate tribasic, also known as ammonium citrate, is a white crystalline powder that is a citrate salt in which all three carboxy groups are deprotonated and associated with ammonium ions as counter-cations. It is a water-soluble salt of ammonia and citric acid, commonly used in various industries due to its unique properties.
Uses
Used in Chemical Analysis:
Ammonium citrate tribasic is used as a chemical reagent for determining the efficient phosphate levels in phosphate salts and fertilizer.
Used in Water Treatment Industry:
Ammonium citrate tribasic is used as a buffering agent and emulsifier in water treatment processes.
Used in Food Industry:
Ammonium citrate tribasic is used as a buffering agent and emulsifier, contributing to the stability and texture of various food products.
Used in Electroplating Industry:
Ammonium citrate tribasic is used as a non-cyanide plating complexing agent, offering an environmentally friendly alternative in the electroplating process.
Used in Machinery Industry:
Ammonium citrate tribasic is used for preparing anti-rust agents, protecting metal surfaces from corrosion.
Used in Metal Surface Cleaning:
Ammonium citrate tribasic is used for cleaning metal surfaces, particularly in the petroleum pipeline cleaning process.
Used in Ceramic Industry:
Ammonium citrate tribasic is used as a ceramic dispersant, improving the uniformity and quality of ceramic products.
Used in Detergent Material:
Ammonium citrate tribasic is used as a component in the formulation of detergents, enhancing their cleaning capabilities.
Used in Soil Improvement:
Ammonium citrate tribasic is used as a component in soil improvement agents, promoting better soil structure and nutrient availability for plants.
Used in Medical and Electronics Industries:
Ammonium citrate tribasic is used as an auxiliary infiltration agent in both the medical and electronics industries, aiding in the manufacturing processes of various products.
Agricultural Uses:
Ammonium citrate is used in a neutral solution for determining the phosphorus content of phosphate fertilizers, such as calcium hydrogen phosphate (CaHPO4). The extraction of phosphate with 1N ammonium citrate is carried out routinely for 30 minutes, first at room temperature and then at 40℃. 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 and is considered 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.

Check Digit Verification of cas no
The CAS Registry Mumber 3458-72-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,5 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3458-72:
(6*3)+(5*4)+(4*5)+(3*8)+(2*7)+(1*2)=98
98 % 10 = 8
So 3458-72-8 is a valid CAS Registry Number.

PROCESSES FOR PRODUCING NH4+ -OOC-R-COOH COMPOUNDS FROM FERMENTATION BROTHS CONTAINING NH4+ -OOC-R-COO-NH4+COMPOUNDS AND/OR HOOC-R-COOH COMPOUND ACIDS, AND CONVERSION OF NH4+ -OOC-R-COOH COMPOUNDS TO HOOC-R-COOH COMPOUND ACIDS

Page/Page column 31, (2011/11/13)
A process for making a NH4+ OOC-R-COOH compound from a clarified NH4+ OOC- R-COO' NH4+ compound-containing fermentation broth includes (a) distilling the broth to form an overhead that includes water and ammonia, and a liquid bottoms that includes a NH4+ OOC~R~COOH compound, at least some of a NH4+ QOC-R-COO" NH4+ compound, and at least about 20 wt% water; (b) cooling the bottoms to a temperature sufficient to cause the bottoms to separate into a NH4+ OOC-R~C00' NH4+ compound-containing liquid portion in contact with a NH4+ OOC-R-COOH compoond-containing solid portion that is substantially free of the NH4+ OOC-R-COO" NH4+compound; (c) separating the solid portion from the liquid portion; and (d) recovering the solid portion.
