Dear All,

 

a useful source of interesting chemicals are found "locked" up within the plastics we consume each day. Is there a simple and clean method of extracting say terepthalic acid and other derivatives from these?

I believe terepthalic acid can be extracted using a simple saponification reaction, with ethylene glycol as the solvent.
