Method for the Continuous Production of Nanoparticulate Metal Oxides in Solvents Containing Polyol

The present invention relates to a method for the continuous production of at least one metal oxide containing nanoparticles, consisting of the following steps: a) preparation of a reaction mixture containing at least one precursor compound of the at least one metal oxide and at least one oxygen donor in a solvent which contains at least one polyol, at a temperature T1 from 0 DEG C to 150 DEG C; b) heating of the reaction mixture prepared in step a) to a temperature T2 of 130 DEG C to 350 DEG C, wherein the at least one metal oxide containing nanoparticles is obtained; and c) cooling down of the reaction mixture from step b) containing the nanoparticles to a temperature T3 of 0 DEG C to 70 DEG C.
