Verfahren zur Reinigung von Aluminiumsulfat
Aluminium sulphate soln. purification. Al2(SO4)3 solns. contg. Fe and Cr, and Ti and/or Zr are purified by treatment with an oxidizer (pref. Cl2), pref. at 150 - 177 degrees C and 3.5 - 14 atm.; and then contacted with a H2O - insol. amine, pref. lauryl (trialkyl-methyl)amine in petroleum distillate...

Cl2), pref. at 150 - 177 degrees C and 3.5 - 14 atm.; and then contacted with a H2O - insol. amine, pref. lauryl (trialkyl-methyl)amine in petroleum distillate, as ion-exchanger. The ion-exchange liquid is regenerated with is not 6% H2SO4, treated with 10 - 20 Na2CO3 soln. to reduce sulphonate to is not >25%, and recirculated. |
