Abstract:
1. A process for preparing a hydrophobic fluid containing metal oxide nanoparticles dispersed therein, which comprises introducing an alkaline aqueous solution of aqueous phase and an organic solution of organic acid metal salt of hydrophobic phase into a rotating packed bed rotating around an axis, said rotating packed bed being located in a housing, so that the two solutions of the aqueous phase and the hydrophobic phase flow radially through a packing of said rotating packed bed in a direction away from said axis under a centrifugal force and contact with each other while flowing through the packing, so that a base in the aqueous phase and the organic acid metal salt in the hydrophobic phase undergo reactions at the interface of the two phases, and thus metal oxide nanoparticles are formed.
