ATMP or amino trimethylene phosphonic acid is a phosphonic acid with chemical formula N(CH2PO3H2)3. It has chelating properties. It can be synthesized from the Mannich-type reaction of ammonia, formaldehyde, and phosphorous acid.

Phosphoric acid that has many uses in industrial applications

Phosphoric acid Properties:
It is Colorless, transparent and syrupy liquid; It is too odorless and tastes very sour; its melting point is 42.35 ; it is so easily soluble in water and resolves in ethanol; it may be irritate human skin to cause phlogosis and destroy the issue of human body; it has got hydroscopic.

atmp 50Phosphoric acid Uses:
The technical grade phosphoric acid may be used to produce variety of phosphates, electrolyte treatment liquids such as chemical treatment liquids, refractory mortar with phosphoric acid and inorganic cohere ant. It is also used as a catalyst, drying agent and cleaner. In coating industry it is used as a rust-proof coating for metals.

It is used most commonly in laboratory preparation of hydrogen halides. It is also used as a rust converter (often called naval jelly or rust killer) for ATMP 50 converting rust into ferric phosphate. Thus it is efficient for removing rust. It is a chemical which is produced in large quantities in food industry. It is cheaply produced.
 
Hence it can be used for providing sour or tangy taste to the processed food. Sometimes it is used for the extraction of citric acid in food industry. It is used in the medical field, basically by the dentists for the correction of irregularities of the teeth (orthodontics) and for dealing with the anatomy, development and diseases of the teeth (dentistry) as an etching solution. It is also used as a teeth whitener to eliminate plaque. It is also the basic constituent in over-the-counter anti-nausea medications which contains high levels of fructose and glucose.

Stating the industrial uses, phosphoric acid is also used as an external standard for phosphorus-31 nuclear magnetic resonance (NMR). In the industrial area it is required for the process used for separating mixtures due to differences in absorbency that is chromatography. It is useful in making phosphoric acid fuel cells, where in it is used as the electrolyte. If one puts two to three drops of phosphoric acid in a gallon of distilled water, it acts as electrolyte in oxy-hydrogen generators.
 
Copper electro polishing is done by using phosphoric acid as an electrolyte. Also this form of phosphoric acid as an electrolyte is used for circuit board planarization and for filing rough edges on work piece. While carrying out the Wentworth Process for activated carbon production, phosphoric acid is used as oxidizing agent.

It is a wet etching agent and hence is commonly used to make impressions on surface. To etch silicon nitride hot phosphoric acid is used in micro fabrication. Due to its defined properties phosphoric acid is also used by construction traders as a cleanser to remove mineral deposits on the sites. It can be used for removing hard water stains as well. It is also used as an aid to soldering in for example in model rail roaders. Phosphoric acid should be stored in a tight container and the area around should be cool, dry and well ventilated.

Hence phosphoric acid is a chemical having abundant uses in industrial applications.
