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 a catalyst?
A catalyst is a substance that increase the rate of chemical reaction without itself undergoing any permanent chemical changeb
Q:What is positive and negative catalyst in chemistry?
Negative catalysts are, on the other hand, slowing down the positive reaction rate at the same time
Q:Can a catalyst be present in the rate equation?
Any reaction with a finite amount of reactants has a half-life, whether it's first order, second order, zero order or complex order. The half-life (t½) is defined as the time taken for the reaction to go half-way to completion. If the reaction is: A + B ---products and A is in excess, then t½ will be the time taken for half of B to be used up. For all reactions, then, you get a decay curve. For zero-order reactions, this 'curve' is a straight line, but for all other orders, the curve is an actual curve and it is quite difficult to distinguish, by visual inspection alone, whether it is exponential (indicating a first-order reaction) or hyperbolic (indicating a second or higher order reaction).
Q:Chemical Glossary: Catalyst
The catalyst is a substance that can change the rate of the reaction without changing the standard of the reaction Gibbs free, according to the definition of the International Pure and Applied Chemistry (IUPAC) in 1981, Enthalpy change. This effect is called catalysis. The reaction involving the catalyst is a catalytic reaction.
Q:How does catalyst aid a chemical reaction?
A catalyst will change the activation time; in a faster way. Hence the reaction will worke quicker. It is kind of like Nitrous in a car. It speeds up the engine, which would be kind of comparabale to two substances.
Q:Which of the following are true about catalysts?
1, 3, 5, 6, 7. 2 is incorrect, catalysts are written above the reaction arrow. 4 is incorrect, catalysts decrease the activation energy thus increasing the rate of reaction (see 7) 8 is incorrect, catalysts are not used up (or if they are, they are also regenerated by a different reaction so that they maintain a constant concentration). edit: about 5, yes i think the answer below is correct, 5 is false actually. catalysts speed up both the forward and the reverse reaction so the equilibrium constant is unchanged. however, 1 is true i think: catalysts can provide a lower energy pathway by way of bringing the reactants together in the correct orientation (rather than random orientations).
Q:A catalyst?
A catalyst does not ever become part of the chemical change. As far as I know, it always speeds up the reaction, but I could be wrong on that if there is only one correct answer. For sure, it's never changed by the reaction. That is part of a catalyst's definition.
Q:How does the catalyst generally add to the organic chemical reaction?
In the case of heterogeneous catalysis, the specific surface of the catalyst, in addition to the activity of the catalyst, is an important factor in determining the reaction rate, which means that the specific surface for catalysis is large and the reaction is as fast as the whole. So the overall principle in understanding the activity of the premise of the catalyst, would like to quickly add a little more.
Q:Explain, using an example, how a heterogeneous catalyst works?
Because of the production of photochemical oxidants from NOx reacting with hydrocarbons in sunlight Noxer blocks are used to rid the NOx from the surroundings through The titanium dioxide (TiO2) on the bocks absorbs ultra-pink radiation from daylight which excites its electrons to a bigger orbital. On the outside of the crystals of TiO2 a reaction happens between oxygen and a high power electron from the TiO2. O2 + e־ --O2 ־ The excessive vigor electron is then given back to the TiO2 when water then reacts with the oxygen to present H2 O + O2 --H+ + O2 ־ + OH Nitrogen dioxide is oxidised to nitrate ions as a result of the hydroxyl radical being an awfully strong oxidising agent NO2 + OH --H+ + NO3 ־ The superoxide from response 3 also varieties nitrate ions from nitrogen monoxide. NO + O2 ־ --NO3 ־ This nitrate is washed away through rain or combines with the concrete within the block.
Q:Horseradish enzyme catalyzed Luminol chemiluminescence reaction
Disinfectant ah ~ bleach ah ~ ~ take this kind of thing to wash the blood once something can interfere with Lumino identification. So that want to do bad things must be a good plan. Lumino in the presence of copper, copper alloy, horseradish or some bleach in the presence of fluorescence. So if the scene of the crime was bleached
