Styrosolve
« on: August 06, 2008, 09:35:26 AM »
Hey! Good day guys!

Can anyone help me here?

Could anyone explain to me the process of recycling styrofoam by using Styrosolve?

Here's the link http://www.blueearthsolutions.com/product_StyroSolve.php

How do they make it so that when they put in the alcohol, the liquified polystyrene separates from the styrosolve? It says that there is an ester involved. Could someone help me on this?

Thanks in advance and more power! :D

It looks like a patented process, I doubt that information is just lying around.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Cant it just be re-precipitated out by dropping it into an excess of non solvent? ...

..  just had a look at their web site and it suggests that they evaporate the 'styrosolve' off and recollect the solvent and pelletise the polystyrene to return to feedstock.

They dissolve expanded polystyrene in solvent then evapourate off the solvent to give polystyrene.  Whats to explain?

This is just for the video demo and polystyrene is not soluble in IPA so it comes out of solution.

I wonder if Styrosolve smells like acetone?
