Subject: RE: [DCHAS-L] Peroxide formers

There will probably some discussion on this, but anecdotal data seems to indicate that an anhydrous peroxide-former tends to form peroxides faster than one that is hydrated or at least contaminated with a little water.  You didn=92t ask but watch out for anesthetic grade diethyl ether in =BC pound cans.  Often times the only inhibitor is a copper lining in the can.  The lining is probably good for weeks to months, maybe a year.  Unfortunately, a lot of those small cans are tucked away for years to decades.
