Ethylene diamine tetraacetic acid (EDTA)
Product name: EDTA
Molecular formula: C10H16N2O8
Molecular weight: M=292.2
CAS number: 60-00-4<\/p>\n\n\n\n


EDTA is a representative substance of chelating agents<\/strong>, and various metal salts of EDTA are often used in practical applications.
EDTA Acid is insoluble in cold water<\/strong> and slightly soluble in boiling water.
However, both EDTA disodium and EDTA tetrasodium are easily soluble in water<\/strong> and are often used in various aqueous solutions.
We also provides EDTA metal salts, such as disodium EDTA and tetrasodium EDTA<\/a>.<\/strong><\/p>\n\n\n\n

Chloride (calculated as Cl)% \u2264 0.05
Sulfate (calculated as SO4)% \u2264 0.05
Heavy metals (calculated as Pb)% \u2264 0.001
Iron (calculated as Fe)% \u2264 0.001
Chelation value: mgCaCO3\/g \u2265 339
PH value (5% aqueous solution) 2.8-3.0
Appearance: white crystalline powder<\/p>\n\n\n\n

Properties:
<\/strong>EDTA acid is a white crystalline powder with a melting point of 240 \u2103 (decomposition); at 150 \u2103, it shows a tendency to remove carboxyl groups.<\/p>\n\n\n\n

EDTA acid is soluble in alkaline solutions<\/strong>, such as solutions of sodium hydroxide, sodium carbonate, and ammonia.<\/p>\n\n\n\n

EDTA acid is insoluble<\/strong> in cold water, alcohol, and general organic solvents. The solubility in water is only 0.5g\/L (25\u2103).
Slightly soluble in hot water, soluble in 160 parts of boiling water.<\/p>\n\n\n\n


Uses:
<\/strong>EDTA has a wide range of uses and is a representative substance of chelating agents. EDTA acid can form stable water-soluble complexes with alkali metals, rare earth elements, and transition metals. <\/p>\n\n\n\n

EDTA is widely used in polymer chemistry industry, daily chemical industry, paper industry, pharmaceutical industry, agriculture, textile printing and dyeing industry, aquaculture, photographic chemicals, oilfield chemicals, water treatment agents, boiler cleaning agents and analytical reagents.<\/p>\n\n\n\n

EDTA Acid<\/strong> is insoluble in cold water<\/strong> and slightly soluble in boiling water, but soluble in alkaline solutions, such as sodium hydroxide.
EDTA sodium<\/a> <\/strong>are easily soluble in water<\/strong> and are often used in various aqueous solutions. <\/p>\n\n\n\n

Packaging:
<\/strong>25kg\/bag or according to customer requirements
Store in a dry and ventilated warehouse, avoid direct sunlight, and stack gently.<\/p>\n","protected":false},"excerpt":{"rendered":"
