Abstract
The present invention relates to innovative nanoparticles, to a process for preparing nanoparticles by recrystallization, and to the use thereof.
Claims14
A process comprising:
- I) preparing a water-in-oil emulsion comprising
- A) an aqueous solution comprising one or more water-soluble compounds selected from the group consisting of lithium molybdate, sodium molybdate, zinc molybdate and mixtures thereof,
- B) an organic solvent and
- C) a stabilizer;
- and
- II) removing water from the emulsion down to a residual water content of not more than 2% by weight, to provide organic media-dispersible nanoparticles of the one or more water-soluble compounds.
