EDTA(Ethylene diamine tetraacetic acid)
he PerformanceThe ethylene diamine four ethanoic acid are one kind of white crystallization powder, melting point 240 °C (decomposition);The solubility in the water the solubility is 0.5g/L (25 °C),It doesn't dissolve in the common organic solvent,but it is able to dissolve in 160 boiling water and sodium hydroxide such as alkazid .When it reaches 150°C,the rendency of taking off the carboxyl will display.
The mainusegeEDTA is wide-used.Which is the cheating representative substance .It can form the stable water-solube compound witn alkaline metal,the rare-earth element and the transition metal etc.It is widely applied polymer chemistry industry,the everyday use chemical industry, the papermaking industry, the pharmaceutical industry, the agriculture, the textile printing industry, the photography chemical, the oil field chemical,the water treatment medicinal preparation, the boiler cleansing agent and the analytical reagent. In addition ,the EDTA can make rapid detoxication by pumping eht harmful radicative metal from the human body.
PackingThe packing material is kraft paper established bag with the 25kg insode lining palstic bag.It can also be packed according the customer 's request. The storing guides against the exposes to the sun,the moisture and the fire.It showld be stored as non- dangerous material
