Pentasodium Salt of Ethylene Diamine Tetra (Methylene Phosphonic Acid) (EDTMP.Na5)
CAS No. 7651-99-2 Molecular Formula: C6H15O12N2P4Na5 Molecular weight: 546.13
Properties:
EDTMP•Na5 is a neutral solid product. It is nitrogenous organic polyphosphonic acid, which is a part of cathodic corrosion inhibitor. EDTMP•Na5 can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. EDTMP•Na5 has good scale inhibition property under temperature 200ºC. EDTMP•Na5 can dissociate into 8 positive-negative ions, thus can chelate with more than two metal ions to form more than two polymer reticulation complex, the complex can be quickly dissolved in water to destroy the normal crystallization of calcium scale. EDTMP•Na5 shows better scale inhibition effects to calcium sulfate and barium sulfate.
EDTMP•Na5 can be used as scale and corrosion inhibitor for circulating water and boiler water system, chelating agent in non-cyanide electroplating, water-softening agent in dyeing industry, etc.
The solid state EDTMP•Na5 is slightly easy to deliquescence, convenient in transportation and suitable for usage in winter and freezing districts.

Shandong Xintai Water Treatment Technology Co., Ltd. is the professional water treatment chemicals manufacturer in China, the company sites at the east of Zao Zhuang City, Shan Dong Province, China where has comfortable climate, beautiful scenery and convinent transportation.
The product families include organic phosphonic series, organic phosphate salt, corrosion inhibitors, chelating agents, dispersants, RO membrane chemicals and etc., covering wide ranges from single to complex agents. The products are widely used in circulating water system, boiler and heating water system in fields such as steel & iron, petrochemcal, power plant and medical industries etc. To satisfy the need of different fields, some solid products such as organophosphoric acids and their sodium salts are developed recently in our factory, including high pure grade and ordinary grade. Some polymer solid products have also been developed. To cooperate with our clients for water quality analysis and treatment process planning, we have set up a synthesis and application laboratory, several research projects are done in this laboratory.
Our Sales characteristics: Pay attention to manufacture of water treatment chemicals, preferably as a workshop of water treatment field.
Ideal clients: Intermediary buyers of water treatment chemicals, not terminal business. Free supply services of water quality analysis, prescription screening, operation planning draft and spot supervision. Supply new product development and trial-produce, make trial product on client order.
Obtain ISO9001, 14001, 45001 system certificate, and make sure quality stable.
It owns independent import and export rights, and products are sold all over the world, and highly approved by clients.
