olecular formula: c10h16o8n2
molecular weight: 292.24
cas no.:60-00-4
property: edta is a white crystal powder. its melting point is 240 °c(decomposition). its dissolving degree in water is 0.5g/l (25°c). it is insoluble in common organic solvents. it is soluble in boiling water 160 times as much, and soluble in alkali solvents like sodium hydroxide. at 150°c, it shows the tendency to depart from carboxyl.

packing:
net each in 25kg plastic woven bag, lined with pe bag.
usage:
as an agent for complexation. edta is mainly used for water treatment, as an additive to detergent, a chemical for photography, paper-making, and oil-field. it is also used as detergent for boiler cleaning and reagent in chemical analysis.
storage:
be stored on shelves in dry and ventilated storehouse. avoid direct sunshine, humidity, breakage of the bags and contamination.
