Introduction


EDTA, or ethylene diamine tetraacetic acid, is a chelating agent widely used in industrial, foods and medical fields. EDTA is synthesized by the alkaline cyanomethylation of ethylenediamine by means of sodium cyanide and formaldehyde. The process of chelation stabilizes the metal ion by preventing it from chemical reacting with any other substances. EDTA is produced as several salts, notably disodium EDTA and calcium disodium EDTA.

Application:

EDTA is an important chelating agent with wide application. It can be used in detergents, dyeing adjuvant, processing agent for fibers, cosmetic additive, food additive, blood anticoagulants, water treatment agent and agriculture 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 salts and iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum and other salts, which have different uses.

In addition, EDTA can also be used to detoxify harmful radioactive metals rapidly excreted from the human body.

 

FAQ
1. What’s the differences between EDTA and EDTA sodium salts?
Under the same alkaline condition, the chelating ability is EDTA (acid)> EDTA 2NA > EDTA 4NA.
The solubility of EDTA acid and EDTA 2NA in water is smaller than EDTA 4NA.
So according to the PH of using environment and solubility, different EDTA products are required.
2. How many tons per container loaded?
For EDTA 2Na, 18/21MT per 20FCL.
For EDTA 4Na, 20/24MT per 20FCL.
For EDTA Acid, 20/22MT per 20FCL.
3. Is OEM packages available?
Yes, MOQ for OEM is 20MT. We can customize shipping mark label and also bag.
4. Do you have jumbo bags?
We have 1ton bag for EDTA, and 850kg bag for EDTA 2Na.
5. What’s the delivery time?
1-5tons, leading time in 7 working days.
More than 5 tons, leading time in 10-15 working days.
6. What about the quality.
We supply specification in industrial, food and also cosmetic grades.
If special requirements about the index and quality, kindly let us know and we will meet.
7. What about the production capacity?
Production capacity for EDTA sodium salts is 26,000tons per year and for EDTA Acid is 50,000tons per year.
8. How to get sample?
Free sample for 100g under collect express account. Kindly contact sales manager for more info.
