PAPEMP is a new kind of water treatment agent. PAPEMP has high chelation and dispersion effects, high value of calcium tolerance, and good scale inhibition effects.
Molecular weight: about 600
Properties:
PAPEMP can be used as scale and corrosion inhibitor in circulating cool water system and oilfield refill water system in situations of high hardness, high alkali and high pH value. PAPEMP has excellent scale inhibition ability to calcium carbonate, calcium sulfate and calcium phosphate. PAPEMP can efficiently inhibit the formation of silica scale, stabilize metal ions such as Zn, Mn and Fe.
Vcycletech PAPEMP can be used as scale inhibitor for reverse osmosis system and multistep flash vaporization system in which high salt concentration, high turbidity and high temperature are usually encountered (such as high temperature and high turbidity in coal vaporization system), accessory agent for woven & dyeing (for example, yellow turnback inhibition agent), as alternatives of EDTA, DTPA and NTA .

Ethylene Diamine Tetra (Methylene Phosphonic Acid) EDTMPA (Solid)

CAS No 1429-50-1 Dequest: 2040

Molecular Formula: C6H20 N2O12P4 Molecular weight: 436.13

Structural Formula:



Properties:
EDTMPA is white crystal powder at room temperature, with melting point 215-217íµ, hard to be dissolved in water, the solubility is less that 5% at room temperature, easy dissolved in ammonia. EDTMPA has strong metal ion chelating capacity, whose chelating constant with cuprum ion is larger than that of EDTA.

EDTMPA has high capacity for chelating metal ions. The complex constant with Cu is the largest in all chelating agents including EDTA. EDTMPA is a kind of high-pure grade reagent and innocuous, it can be used as detergent in semiconductor chip to prepare integrated circuit, as carrying agent for radioelement in medical industry, and as agent for inspection and therapy. The chelating capacity of EDTMPA largely exceed that of EDTA and DTPA, and can replace EDTA for chelating agent at almost any situation.

The word "Chelate" is derived from the Greek word for "Claw". Metallic chelates are a complex of a metal ion bound to an organic molecule (ligand).

Metal ions are important minerals for plants. They are required by plants in small amounts, and therefore are being refered to as 'Micronutrients. Their deficiencies result in yellowing of leaves, retarded growth and general low quality crops.

Chelated compounds are more stable than non-chelated compounds. Therefore, metallic chelates are widely used in agriculture as micronutrient fertilizers to supply plants with Iron, Manganese, Zinc and Copper. The most common chelates used in agriculture are EDTA, DTPA and EDDHA.


How Does a Cheate Work?

Metal chelation is important because it makes metal ions more available for uptake by plants. Positively charged metal ions, such as Zn+2, Mn+2, Cu+2 and Fe+2, readily react with negatively charged hydroxide ions (OH-), making them unavailable to plants. OH- ions are abundant in alkaline or neutral soils and soil-less media.

The ligand (a molecule that binds to a central metal atom) coats the metal ion, protecting it from the surrounding OH- ions. The complex can then be easily absorbed by the plant, where it is being degraded and consumed as micronutrients.
