METHOD OF OBTAINING COLLOIDAL SOLUTIONS OF ZINC OXIDE IN NONPOLAR SOLVENTS

摘要

1. A process for the preparation of colloidal solutions of zinc oxide in non-polar solvents, comprising heating a reaction mixture of oleylamine, oleic acid and the inorganic zinc-containing precursor in an inert atmosphere, isothermal exposure, the addition of polar solvent, the separation of coagulated nanoparticles centrifugation redispersion precipitate in a nonpolar solvent, wherein in that the zinc-containing precursor using zinc nitrate implementation heating the reaction mixture to 80-100 ° C for 15-30 min and then heated at a temperature of 200-250 ° C for 1-4 hours.! 2. A method according to claim 1, characterized in that the starting reaction mixture was further added diphenyl ether. ! 3. A method according to claim 1, characterized in that the starting reaction mixture was further added hexadecane.
