摘要:

The distribution of zinc between the toluene phase containing trioctylphosphine oxide (TOPO) and the nonaqueous ethylene glycol phase containing either hydrogen or lithium chloride has been investigated by using zinc-65. In the zinc-hydrogen or lithium-chloride-TOPO system, the complex ZnCl2-2TOPO may predominantly occur in the toluene phase, and only mononuclear zinc complexes appear to exist in the two phases.
