Amino-trim methylene phosphonic acid or phosphonic acid is a type of organic phosphate and its chemical formula is C3H12NO9P3. In the normal state, this substance is in the form of white crystals or white powder.
This organic phosphate is easily soluble in water and it has good chemical stability and it is difficult to hydrolyze in solution form. Aqueous solutions of Amino-trim methylene phosphonic acid are used as anti-fouling and anti-corrosion agents, this action done by absorbing calcium carbonate.
The main application of ATMP is in water treatment industries and in particular phosphonates are very useful to prevent the formation of water-soluble salts such as calcium carbonate, phosphates, calcium sulfate, and often. This substance is often combined with organophosphorus acids, copolymers, and Zinc salts are used to make organic water treatment compounds.
PHYSICAL AND CHEMICAL PROPERTIES OF ATMP:
Amino-trim methylene phosphonic acid has higher antifouling properties at low temperatures and high concentrations and it has good stability in terms of temperature and this property is more on carbonate than other materials. The most important physical and chemical properties of this organic material can be summarized in the following table:
|Molecular Weight (g/mol)||299.04|
|Boiling Point (°C)||746|
|Melting Point (°C)||200|
|Solubility in water (g/100 mL)||61|
SYNTHESIS AND PRODUCTION OF ATMP:
Amino-trim methylene phosphonic acid can be produced in different ways:
One method is the reaction of ammonium chloride with phosphoric acid and hydrochloric acid. To perform this reaction, a list of raw materials is used at high concentrations, and the reaction temperature is set at about 100 ° C. The reaction continues with the Slowly addition of formaldehyde to the reactor and after about two hours, with the help of centrifuge separation operations, we can obtain the desired material.
The second method of synthesis is known as the Mannich method. We use a two-step process at first a part of the material is synthesized and then through hydrolysis, we reach the final product, during this process formaldehyde with diethyl and amine reacts, and by adding diethyl phosphite to the intermediate and finally by hydrolyzing this material, the desired product is produced.
In the third method, which is an interesting initiative, we can combine phosphonic acid to a special polymer, this polymer can be polyethyleneimine. by adding three substances amide, formaldehyde, and phosphorus trichloride, and decomposing polyethyleneimine, the desired product is produced.
Application and uses of ATMP:
Sedimentation and corrosion of metals used in power plants, refineries, petrochemicals, and water and sewage pipelines is an important issue that has recently attracted the attention of many researchers, ATMP can play a key role in preventing the formation of sediment on these Metals and protect them against corrosion.
It can be used with some organic acids or salts to purify water in water cooling systems.
This material is used in various industries, which are mentioned below:
- This organic phosphate is used in the agricultural industry, animal husbandry, animal feed, and in the production of agricultural products.
- It is used in the production of detergent products used in household uses and bleaches as a bleaching agent.
- ATMP Used in the cosmetics industry and the production of hair dyes and cosmetics, such as food dyes and pigments.
- It is used in the pharmaceutical industry in the production of various drugs, especially drugs-related to veterinary medicine.
- It is also used as an antifreeze.
The Uses of ATMP in water treatment:
Today, organic materials are widely used in the water treatment industry. In particular, phosphonates are very useful for preventing the formation of water-soluble salts such as calcium carbonate, phosphates, calcium sulfate.
Some water treatment systems use biocides to prevent the activity of germs. Some of these biocides are strong oxidants and cause oxidative degradation of existing chemicals. In this case, after adding amino trimethylene phosphonic acid, this substance reacts quickly with biocides and prevents the destruction of other chemicals.
ATMP is considered an acidic chemical and all safety and health points must be observed when you are working with it. Be sure to wear safety glasses, gloves, and special clothing.
Direct contact of this substance with the body can cause inflammation and burning sensation or pain. In case of direct contact with the skin or eyes, be sure to wash that area with soap and water, and if the discomfort continues, go to the centers. See therapist.
transporting and storage:
To store this material, keep containers away from heat and direct sunlight.
