In the present work aqueous sulfurid acid was extracted with trialkylamine dissolved in mixtures of tributyl phosphate and de-aromatized kerosene and in pute TBC. The "physical" extraction of the acid with TBF was also determined. The experiment were done at 25°C. The equilibrium acid concentrations in both phases and the content of co-extracted water in organic phase were measured.

V práci byla extrahována sírová kyselina trialkylaminem rozpuštěným v tributylfosfátu, nebo ve směích tributylfosfátu s dearomatizovaným petrolejem. Byla stanovena také „fyzikální“ extrakce kyseliny čistým TBF. Experimenty byly prováděny při 250C. Byly měřeny koncentrae kyseliny v obou fázích a obsah koextrahované vody v organické fázi.
