propylene oxide in storage
« on: June 10, 2013, 09:57:56 AM »
I am considering using propylene oxide in an alkylation of cysteine.  We have some in bottle in a can that is at least 10 years old, but it has never been opened.  I am not aware of any decomposition problems.  Is it OK to use as is?

If it hasn't been opened then it should be OK, run an NMR to be sure.

Styrene oxide polymerizes pretty fast on storage. I don't know if PO has a similar problem.
