Rubidium and Caesium
Will either of them react with tetrahydronaphthalene or tertiary butanol?
I need a inert solvent other than mineral oil that they will not react with.

This thread should have been posted in beginnings.
Neither of them will reduce tertiary butanol, but they will react. Benzene and tetrahydronaphthalene are completely compatible with Rb and
Cs, it will not actually dissolve. For highly reactive difficult to dissolve substances, often just colloidal dispersions are used.
Perhaps the solvent N,N-Diisopropylethylamine might work. The alkali metals are also soluble in anhydrous liquid ammonia, forming blue solutions.

What do you think? tBuOH is an alcohol what has an OH group where the hydrogen could be removed with lithium, sodium, potassium ect. while it forms
alkali-t-butoxides. If you would add it to cesium it would form Cs-butoxide what is a hygroscopic white powder. The reaction is not so violent, it is
also used to get rid of metallic Cs (I used it for that).
And also for the tetrahydronaphtalene, I have posted not long ago in a topic what YOU have opened from the same:
"A little more info from Rb/Cs chemistry: mixing metallic Cs with benzene will yield a black amorphous participate what will explode on contact on
almost everything, it has a chemical formula: C6H6Cs6.
Mixing metallic Cs with toluene will also end up with a reaction and yield C6H5CH2Cs. So be smart what kind of solvent would you want to use. "
Why do you open several topics from the same when these questions are already answered? Use the search button or google it.
I have a blog where I post my pictures from my work: http://labphoto.tumblr.com/
-Pictures from chemistry, check it out(:

For potassium production tertiary butanol is used as a catalyst and when it is used no butoxide appear to form. You haven't simply stated if there is
a reaction between caesium and tetrahydronaphthalene, and you've completely left out rubidium reactions.

So Anderhoveland, you think that tetrahydronaphthalene and rubidium and caesium won't react? Is that right?

Read the sticky thread on potassium production: t-butanol forms a butoxide with K, which is PRECISELY why it's a catalyst for the reduction of KOH
with Mg in inert media.
Cs and Rb also form butoxides, even more vigorously than K and Na. And the reduction of their hydroxides with Mg also depends on it.
Tetrahydronaphtalene ('Tetralin') doesn't react with K and can be used as an inert solvent for the KOH/Mg reaction, as demonstrated by Nurdrage in
that thread. I don't know how it behaves towards Rb or Cs.
Fully saturated alkanes are definitely inert towards Rb and Cs, at least up to 200 C. The patent mentioned in the K sticky thread mentions decane for
Cs production.
