抄録

Mechanism of acid extraction by tri-n-octylaminebenzene mixed solvent was studied on the standpoint of equilibrium, and the mechanism of acid transfer was clarified on the basis of the above results, using cylindrical lens Schlieren apparatus. The reactions accompanied with extraction are fast enough and the transfer of acid is controlled by diffusion step. Generally speaking, acid in aqueous phase reacts with TOA free from acid or TOA-HX complex on liquidliquid interface and is extracted in the form of TOA-HX or TOA-(HX) 2. In case of the formation of TOA-(HX) 2, reaction plane is formed in organic phase; TOA-(HX) 2+TOA→2TOA-HX. Schlieren method is efficient for the recognition of reaction plane, since the gradient of refractive index varies steeply near the reaction plane.
