EDTA는 킬레이트제의 대표적인 물질로 EDTA의 다양한 금속염이 실용적인 용도로 자주 사용됩니다.
EDTA 산은 차가운 물에 녹지 않고 끓는 물에 약간 녹습니다.
그러나 EDTA 이나트륨과 EDTA 테트라나트륨은 모두 물에 쉽게 용해되며 다양한 수용액에 종종 사용됩니다.
또한 이트륨 EDTA 및 테트라나트륨 EDTA와 같은 EDTA 금속염도 제공합니다.

Appearance: white crystalline powder
Properties:
EDTA acid is a white crystalline powder with a melting point of 240 ℃ (decomposition); at 150 ℃, it shows a tendency to remove carboxyl groups.
EDTA acid is soluble in alkaline solutions, such as solutions of sodium hydroxide, sodium carbonate, and ammonia.
EDTA acid is insoluble in cold water, alcohol, and general organic solvents. The solubility in water is only 0.5g/L (25℃).
Slightly soluble in hot water, soluble in 160 parts of boiling water.
Uses:
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.
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.
EDTA Acid is insoluble in cold water and slightly soluble in boiling water, but soluble in alkaline solutions, such as sodium hydroxide.
EDTA sodium are easily soluble in water and are often used in various aqueous solutions.
Packaging:
25kg/bag or according to customer requirements
Store in a dry and ventilated warehouse, avoid direct sunlight, and stack gently.
