This is a treasure hunt to sit and drink over my morning coffee! Here it goes:
A Wiki- search to get started: https://en.wikipedia.org/wiki/
There's several varieties, so checking each one you have is important. You=E2=80™ll want to weed out the poisons and corrosives from the ones that are actually reactive (DOT Class 4's).
I looked up "azacrowns" first thinking they would be the most likely to be reactive. Here's one example. It's just corrosive:
If they are in liquid form they may be in acetonitrile, THF, methanol, cyclohexane, benzene, or toluene; which means you're back to checking for peroxides:
At the bottom of this Wiki-page you can get to the Sigma Aldrich page and look up the SDS. 18-Crown-6 seems to be nothing, but I would not put it in the trash and freak out everyone down-stream; especially with the ever-present "no data available" throughout SDS.
I hope this gets you started!
Good Afternoon All!
I hope everyone has had a good week-maybe enjoying a little cooler temperatures than we have in Charleston SC. I have a question concerning the disposal of crown ethers. This may be too broad of a question, but are there any special considerations with their disposal? We are trying to rid ourselves of some "legacy" chemicals and I admit that I'm not very familiar with crown ethers. Other ethers can be peroxide-forming and must be handled accordingly. I'm told crown ethers are different, but I would feel better with some other guidance/advice.
Any insight would be greatly appreciated!
