Profitable time?

Wasted my life staying late yesterday; just crap obtained! Never mind, I'm more phlegmatic about it this morning. Column done today also appears to have given me nothing but starting materials and a smidge of other stuff, I'm putting it down to crapness quality of my heterodiene but I *really* dont want to have to distill it again, or, in fact, make some more.

Tuesday today. Must, MUST look up group meeting stuff this evening!
