摘要： 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 Y
1 -R
1 -X-R
2 -Y
2 , wherein - R
1 and R
2 each are the same or different and independently selected from aliphatic groups with from 1 to 20 carbon atoms, - Y
1 and Y
2 each are the same or different and independently selected from OH, NH
2 and SH, and - X is selected from the group consisting of chemical bond, -O-, -S-, -NR
3 -, and CR
4 R
5 , wherein R
3 , R
4 and R
5 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, NH
2 and SH. This invention also relates to metal oxide nanoparticles, to a method of making dispersions of said nanoparticles and to dispersions containing them.
