Product Description:

Product Description:

Amino tris(methylene phosphonic acid)  / Amino Trimethylene Phosphonic Acid/ ATMP / 6419-19-8 /  C3H12NO9P3

CAS No.  6419-19-8

Molecular Formula:   N(CH2PO3H2)3                

Molecular weight:  299.05

Structural Formula:


ATMP has excellent chelation, low threshold inhibition and lattice distortion ability. It can prevent scale formation, calcium carbonate in particular, in water system. ATMP has good chemical stability and is hard to be hydrolyzed in water system. At high concentration, it has good corrosion inhibition.

ATMP is used in industrial circulating cool water system and oilfield water pipeline in fields of thermal power plant and oil refinery plant. ATMP can decrease scale formation and inhibit corrosion of metal equipment and pipeline. ATMP can be used as chelating agent in woven and dyeing industries and as metal surface treatment agent.

The solid state of ATMP is crystal powder, soluble in water, easily deliquescence, suitable for usage in winter and freezing districts. Because of its high purity, it can be used in woven & dyeing industries and as metal surface treatment agent.

Q:What is the quality of the catalyst in the chemical reaction,and how much is the catalyst mass?
You can not calculate this question, the quality of the catalyst before and after the same reaction, how much reaction before the reaction on how much
Q:What is the effect of increasing the amount of catalyst added to a solution?
Adding a catalyst would increase the rate of reaction. This could decrease the activation energy, the amount of kinetic energy needed for the reaction to occur. Hope that helps
Q:High chemistry: Does the catalyst affect the heat and heat of the reaction?
No effect
Q:Why does the chemical and chemical properties change before and after the reaction?
Definition: According to the definition proposed by IUPAC in 1981, the catalyst is a substance that accelerates the rate of the reaction without changing the standard Gibbs free enthalpy change of the reaction. This effect is called catalysis. Involving the presentation of the catalyst for the catalytic reaction
Q:Explain how a catalyst may increase the rate of chemical reaction?
Catalysts lower the activation energy (that is, the energy needed for a reaction to proceed) in either the final product or the intermediates. It can do this in a number of ways, including conformational (shape) changes in the intermediates (such as in complex organic molecules), changing the intermediates that form (alternate reaction pathway) or by changing the reactant in a certain way (like sulfuric acid stripping a proton off of a molecule so that nitric acid can bind to it and nitrate it, which would otherwise be energetically unfavorable). In English, catalysts change the molecules so it doesn't take as much energy for the reaction to take place. Think of jumping a hurdle: the same height on either side of it (reactant and product), but if you lower the hurdle (reduce the activation energy) it's easier to get to the other side.
Q:In the catalyst and light conditions to break down the water to get the chemical equation of hydrogen
2H2O = (light or catalyst) 2H2 ↑ + O2 ↑
Q:reactants are constant or the quality and chemical properties of the catalyst are constant?
The change in chemical reaction rate is the same as the chemical nature and quality
Q:What are the catalysts for making oxygen in chemistry? (At least 8 listed)
Manganese dioxide, iron oxide (red brick powder), copper oxide, ferrous oxide, iron oxide, activated carbon, egg shell, fresh liver, raw potato chips, etc.
Q:What is the difference between biological and chemical catalysts?
catalysts which catalyze the chemical reactions taking place in human body such as enzymes are called bio-catalyst and other one's which are generally used in laboratory by chemists for multiple type of reactions are chemical ctalysts
Q:What is the catalyst for high chemistry?
Concentrated sulfuric acid, NI, barium bromide, copper or silver
