For potassium separation I am searching for an oil slightly heavier than K metal which has a density of 0.86.
Which oil can I use for this? Most oils are 0.8.zoombafu - 13-1-2012 at 14:06
You could use canola oil, it has a density of .92 g/mL.unionised - 13-1-2012 at 16:15
This would have been a good question for the short questions thread.Mr. Wizard - 13-1-2012 at 18:23
More double bonded carbons, and longer chain length equals more density in general, as the ratio of C to H goes up.metalresearcher - 14-1-2012 at 00:04

So, candle wax (i.e. paraffin)? Dr.Bob - 14-1-2012 at 09:33
The only thing that will make the density heavier than 0.9 would be more heteroatoms, like oxygen, sulfer or halogens, and most of them will react
with K in a violet manner. You will be hard pressed to find an oil that dense that in only a hydrocarbon, and I am sure that there is something that
would work, that does not react with K, but it might be pricey. Maybe a Dowtherm oil or some silicon based oil, but make sure they are stable to K
before using.
