Benzaldhyde from styrene////styrene to other compounds

Davyrocket - 14-5-2013 at 11:43

Hi all

Is it actually possible to Oxidise polystyrene
Or styrene to crud benzaldhyde, under some sort of inert
Pressure, at 250 to 300 degrees... :)


Thx the rocket

Why are you so desperately looking for benzaldehyde?

elementcollector1 - 14-5-2013 at 11:59

I looked up benzaldehyde and got a viable source right away - UTFGSE!
(Hint: It can be found in every (good) American grocery store, sometimes in more than one source).

I am totaly in love with the compound
For my soap making:)

Yea I can buy it but it's not the same as making your own:)

Sure, why not? The problem with oxidations, is stopping them, not starting them.

Use the "Search" function. That... should keep you busy for a few weeks.

Thx zed

If anyone has any good refs or links
Out there, for me to study up on styrene to benzaldhyde
Would be much welcome..

I can't purchase benzaldhyde
In the uk....

Thx rocket

Just make it from toluene or benzyl alcohol, it is much easier and much safer aswell.

Or, you know, almonds. I'd imagine an extraction would be possible from dried and then crushed or even powdered almonds.

Yea I appreciate all ideas toluene /benzalchohol, contribution
It's just that styren has got to be
One of the easiest and less expensive
Chemical's to require....

Thx rocket

Yes, but it is not the easiest or cheapest route to your target. Almond extract, cinnamon oil, toluene... All of these are better ideas. Read the huge thread, ,Toluene to Benzaldehyde. It covers more than just the oxidation of toluene.

Hay Bot0nist

Yea I appreciate what you are saying Bot0nist.
But I thought I would start a styren
Thread as it can be a starting point to
Other compounds.

Thx rocket

Do you have a procedure in mind for the oxidation, or is that what your asking? I assume you have searched the other styrene threads for advice on oxidation and possible uses.

benzaldehyde from ozonosis of styrene
https://www.sciencemadness.org/whisper/viewthread.php?tid=22...

Oxidation of Styrene
https://www.sciencemadness.org/whisper/viewthread.php?tid=14...

Oxidation of styrene to phenylacetaldehyde
https://www.sciencemadness.org/whisper/viewthread.php?tid=22...

etc., etc., etc.

Enter "styrene" in the forum search function, select subject only, and read, for days...

Fairly easy to recover Benzaldehyde from oil of Cassia, or Cinnamaldehyde. Or, Cinnamon bark, if that is all you can access.

Just a steam-type distillation under basic conditions.
