Project Description

Version en Español:

Etileno-tetra (metileno fosfónico)

Ethylene Diamine Tetra Methylene Phosphonic Acid, EDTMPA

CAS No.: 1429-50-1
Molecular Formula: C6H20N2O12P4
Molecular weight: 436.13

Structural Formula:

EDTMPA corrosion inhibitor

Properties:

EDTMPA is white crystal powder at room temperature, with melting point 215-217°C. It is hard to be dissolved in water. The solubility is less than 5% at room temperature, easily dissolved in ammonia.

EDTMP acid has strong metal ion chelating capacity, whose chelating constant with cuprum ion is larger than that of EDTA.

EDTMPA has a high capacity for chelating metal ions. The complex constant with Cu is the largest in all chelating agents including EDTA.

EDTMP is a kind of high-pure grade reagent and innocuous, it can be used as a detergent in the semiconductor chip to prepare integrated circuit, as carrying agent for radioelement in the medical industry, and as agent for inspection and therapy.

The chelating capacity of EDTMP largely exceeds that of EDTA and DTPA and can replace EDTA for a chelating agent at almost any situation.
