Introduction

EDTA, or ethylenediaminetetraacetic acid, is a chelating agent widely used in industry,

food and medical fields. EDTA is synthesized by alkaline cyanomethylation of ethylene.

diamine with sodium cyanide and formaldehyde. The chelation process is stabilized

metal ion, preventing it from reacting chemically with any other substances. EDTA is

It is produced in the form of several salts, notably disodium EDTA and calcium disodium EDTA.

Statement:

EDTA is an important chelating agent with wide applications. It can be used in detergents, dye additives, fiber treatment agents, cosmetic additives, food additives, blood anticoagulants, water purification agents, agricultural fertilizers, etc.

EDTA can form stable water-soluble complexes with alkali metals, rare earth elements and transition metals. In addition to sodium salts, there are ammonium and iron salts, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum and other salts that have various uses.

In addition, EDTA can also be used to detoxify harmful radioactive metals, which are quickly eliminated from the human body.

FAQ:

1. What is the difference between sodium salts EDTA and EDTA?

В тех же щелочных условиях хелатирующая способность - EDTA (кислота)> ЭДТА 2NA>EDTA 4NA. The solubility of acid EDTA and EDTA 2NA in water is less than EDTA 4NA. Thus, depending on the pH of the medium and solubility, different EDTA products are required.

2. How many tons of loaded container?

For EDTA 2Na 18/21 MT at 20FCL. For EDTA 4Na 20/24 MT at 20FCL. For acid EDTA 20/22 MT at 20FCL.

3. Are OEM packages available?

Yes, the minimum order quantity for OEM is 20 million tons. We can customize the shipping stamp label as well as the bag.

4. Do you have large bags?

We have 1 ton bag for EDTA and 850 kg bag for 2Na EDTA.

5. What is the delivery time?

1-5tons, delivery time 7 working days. More than 5 tons, delivery time is 10-15 working days.

6. About quality.

We supply specifications of industrial, food grade as well as cosmetic grades. If there are special requirements for index and quality, please let us know and we will comply.

7. How about the production capacity?

The production capacity of EDTA sodium salts is 26 000 tons per year, and EDTA acids are - 50 000 tons per year.
