I know this thread has been inactive for 12 years, but is there any way of converting the spandex polymer, which is made from THF, back to THF?

Where did you get the information that spandex is made of THF? It's an urethane containing polymer, look at the attachment.


edit: now I see what you meant, but I wouldn't expect there to be such a way. Spandex structure doesn't have any tetrahydrofuran-like rings at all.

If anyone in canada requires THF, DMC, glacial acetic acid, toluene and or acetone etc.. I can give you a company name that will ship to individuals without issue. I ordered 4l THF a few years back , the company was a reseller for a chem supply company out east. Prices are reasonable and product is pure. Also they are not a chemical supply company themselves. Just figured I'd offer so long as you don't plaster their name all over SM.

The Furfural link at the beginning of this discussion, no longer links to a Furfural Synthesis.

This is the correct link: http://www.orgsyn.org/demo.aspx?prep=CV1P0280

Furfural to the Carboxylic Acid: http://www.orgsyn.org/demo.aspx?prep=CV1P0276

The Carboxylic acid to Furan: http://www.orgsyn.org/demo.aspx?prep=CV1P0274
