What do you suppose happens when you have a separatory funnel with a slow leak, and material that polymerizes when it contacts air?

This happened over Friday night.



Next day:



BTW, my lab doesn't look like this. We set these up elsewhere, in an un-airconditioned storage area, so the samples would be exposed to the same temperatures as the material out in the plant. No, we do not want this polymerization in our process. Still, it looks kind of cool.
