Are there any tabulated values of dielectric constants of fatty alcohols at high temperature and pressure (250 deg C, 250 bar)? I haven't been able to find any in literature.
Dear Delnaz, thanks for sharing this interesting technical question with the RG community. All I know is that the dielectric constant is inversely proportional to temperature. However, like Rani P Ramachandran
I found no literature references which really answer your question. The experimental conditions (250 deg C, 250 bar) are rather special. Measuring several aliphatic alcohols under these conditions would require the work of an entire master thesis. Sorry for not being able to help you in this case.
