EDTA-Mn CAS 15375-84-5 Manganese disodium EDTA trihydrate

Metal chelate compounds, there are two kinds of existing trace element fertilizers, one is sulfate, such as FeSO4.CuSO4.MnSO4.ZnSO4.MgSO4, and the other is the upgraded product of sulfate, namely sulfate+EDTA•2Na+( Stabilizer urea), the existing sulfate+EDTA•2Na+ (stabilizer urea) preparation method is: the sulfate FeSO4.CuSO4.MnSO4.ZnSO4.MgSO4 is all dissolved in water within 70 ℃ to obtain solution A, and the EDTA • 2Na is completely dissolved in water within 70℃ to obtain solution B. Mix and stir solutions A and B according to the ratio of EDTA•2Na:sulfate:water (molar ratio)=1:0.1~0.5:300~2500 for 0.5 hours, The pH value was adjusted with NaOH, and the finished product was obtained by filtration. This production method has many shortcomings. Manganese disodium EDTA is one of the complex metal salts of EDTA.
