Solvent extraction of hydrofluosilicic acid with alamine 336
(1986) In Canadian Journal of Chemical Engineering 64(3). p.426-431- Abstract
- Extraction constants for the solvent extraction of hydrofluosilicic acid with Alamine 336 have been determined. Two species were identified, (R3NH+ )2 SiF62- and R3NH+ HSiF6, whose respective extraction constants were determined to be log K21 = 7.42 and log K11 = 2.60. For the dissociation of hydrofluosilicic acid the activity coefficient model presented by Bromley was adapted to sulphuric acid and the values used for hydrofluosilicic acid. The effect of the diluent was experimentally investigated.
