Abstract

The current invention relates to a method of making metal oxide nanoparticles comprising the reaction of—at least one metal oxide precursor (P) containing at least one metal (M) with—at least one monofunctional alcohol (A) wherein the hydroxy group is bound to a secondary, tertiary or alpha-unsaturated carbon atom—in the presence of at least one aliphatic compound (F) according to the formula Y¹—R¹—X—R²—Y², wherein—R¹ and R² each are the same or different and independently selected from aliphatic groups with from 1 to 20 carbon atoms, —Y¹ and Y² each are the same or different and independently selected from OH, NH₂ and SH, and —X is selected from the group consisting of chemical bond, —O—, —S—, —NR³—, and CR⁴R⁵, wherein R³, R⁴ and R⁵ each are the same or different and represent a hydrogen atom or an aliphatic group with from 1 to 20 carbon atoms which optionally carries functional groups selected from OH, NH₂ and SH. This invention also relates to metal oxide nanoparticles, to a method of making dispersions of said nanoparticles and to dispersions containing them.
