I want disperse kaolin (crude kaolin) in an organic solvent. when you put crude kaolin in water it disperses in water. BUT which organic solvent will act like water??
You can try very polar solvents:
- protic: methanol, ethanol, isopropanol that will wet the kaolin surface by making hydrogen bonding;
- aprotic: ACN, DMF, DMSO, acetone.
Good luck with the experiments!
Organic solvents won't disperse kaolin. This is why cosmetic manufacturers use surface-modified kaolins when they want to make an oil dispersion. You could try one of those if you aren't 100% committed to using the crude material. They're cheap and readily available.
Try with dichloromethane, it disperses SiO2 perfectly, maybe it can do the same with kaolin since it is inorganic powdered silicate.
