摘要：

The mechanism of tin(IV) extraction with N-benzoyl-N-phenylhydroxylamine from hydrochloric acid media is discussed.The equilibrium Sn(H2O)2CL4 + 2HBPHA ⇌ Sn(BPHA)2CI2 + 2H+ + 2Cl- + 2H2O is proposed on the basis of extraction data, elemental analysis and i.r. spectra. The value of the equilibrium constant is 6.80± 0.02 at 25°C and I = 2. The extracted species is considered to be a mixed neutral complex, SnCl2(BPHA)2. © 1979.
