Descripción

General description

Ammonium phosphate dibasic is a water-soluble ammonium phosphate salt. It is a key component of phosphate fertilizers. It is commonly used as a flame retardant for plywood, paper, and fabrics, as well as a corrosion inhibitor consolidant for degraded carbonatic materials found in old buildings.

Application

Ammonium phosphate dibasic can be used as a catalyst:

To synthesize tetrahydrobenzo[b]pyranderivatives via three‐component condensation reaction.
In the solvent-free Biginelli reactions.
To synthesize bis(indolyl)methanes via solvent-free reaction of indole derivatives and aromatic or aliphatic aldehydes.

Effect of Mg(2+) doping on beta-alpha phase transition in tricalcium phosphate (TCP) bioceramics.

Matteo Frasnelli et al.

Acta biomaterialia, 33, 283-289 (2016-01-23)

The beta to alpha transition in tricalcium phosphate (TCP) bioceramics containing different amount of magnesium was studied in the present work. Mg-doped TCP powder was obtained by solid-state reaction starting from pure calcium carbonate, ammonium phosphate dibasic and magnesium oxide
