I suspect that overly fearful bureaucrats had something to do with this. This is some bad Juju. I would like an explanation as to why this was deleted. I am strongly tempted to make a video to replace this.

Exactly. Make one. He got too big as the king of random on YouTube so he has to follow rules now.

Why have you deleted your potassium videos?

Would it be possible to make Sodium with Sodium Hydroxide and Aluminium rather than the Potassium Hydroxide and Magnesium?

I can't seem to get my hands on the catalyst, is it needed? The catalyst only speeds up the reaction.

wow i love your video. perfect step by step if u have all said materials.

I have spend many hours trying to figure out how this could be done. (somehow an other solvent but water never came to mind long enough to consider it)
but can't the kinetics be improved? isn't there a catalyst which makes it a little bit faster,
no offense, but waiting hour(s) might seem like an eternity.

It only took hours in this video because i used magnesium turnings and i didn't stir it. Basically i wanted the reaction to proceed slow enough that you could see it.

If you use fine magnesium powder, shake/stir the reaction mixture, and use much higher heating (250 Celsius or vigorous reflux), you can be finished in one hour.

that indeed sounds a lot better :-)
thanks for the reply

I want a Nurd Rage t-shirt. Could make it myself i guess but would rather pay you too fund all the great work.

I wonder if I could make Cs by this way

If You do do not put the cesium in water. its a great way to lose some body parts.

author
spinaci (author)9mag92012-01-27

Well, Cs could be ignited just in room temperature. Also Cs is too expensive for losing body parts

Might it be possible to use a mixture of sodium and potassium hydroxides in this reaction to produce sodium? Wouldn't the potassium metal that's produced react with the sodium hydroxide present to produce sodium metal and potassium hydroxide? That way, you could produce a mixture of sodium and potassium.

Fascinating! But, questions:
Once you've got the potassium, what can you do with it?
How on earth do you work out how to do this - how you are going to make the reaction take place?

The video is more or less to explore the science.

A paid chemist needs potassium as a reducing agent and sometimes as a drying agent. Although in practice, they would simply buy potassium directly instead of making their own.

An amateur might want potassium because it has nice flaming reactivity, or they might want it because they honestly need a reducing agent or a drying agent for their own synthetic work. Making it is actually somewhat cheaper than buying it since you don't have to pay hazmat fees to get the precursors.

OFcourse the number of amateurs that have true synthetic intentions with it could probably be counted on one hand.

So overall, the video is to explore the science.

Nice video. In the US patent for this method, the sodium synth uses preformed sodium alcoholate. I'd like to suggest trying n-butanol or n-pentanol as the catalyst.

There is also a published synth using sodium in ethanol to reduce naphthalene to tetralin and then on to decalin. I've actually run this reaction, and yields are a lot higher using a neutral (decane) hydrocarbon with naphthalene dissolved in it, adding sodium, and reducing with ethanol.

You can make tetralin at home? awesome!

how u put it out i got a small fire in a container that has holes in it :O

I love your laugh at 7:16 it's so funny.

Well, alcohol does tend to make things coalesce.

This is quite fascinating to watch ( like all of your videos) good job. Ever think of doing a video on making sodium through the electrolysis of molten sodium chloride?

author
frodobot (author)2011-12-31

Hi,

I love these videos! But you can't click on the How to coalesce potassium video link because of the youtube bar coming up every time :/ Great video though :)

author
NurdRage (author)frodobot2011-12-31

Sorry about that! I fixed it now and made the link squarer. i hope that helps

My brain grows a little each time I watch one of your videos
