Conclusions

  1. 1.

    The systems SiCl4-TBP, GeCl4-TBP, and SnCl4-TBP in hexane (TBP is n-tributyl orthophosphate) were investigated by the method of dielectrometric titratton.

  2. 2.

    No appreciable interaction was detected in the systems SiCl4-TBP and GeCl4-TBP. Successive formation of molecular complexes with 1∶1 and 1∶2 compositions was found in the system SnCl4-TBP.

  3. 3.

    The equilibrium concentrations in reactions of complex formation of SnCl4 with TBP were calculated with an electronic computer, and the orders of the corresponding equilibrium constants were estimated.

  4. 4.

    The dipole moments of the complexes formed were determined, and hypotheses concerning their structure were advanced.
