I've been a bit quiet on here of late. That's chiefly because I've been busy with one thing and another and I think I'd lose some serious brownie points for blogging at work. And often the impetus to blog in the evening is not high; I would rather watch the hockey and cackle to myself at being second in the chemistry department pool and the thought of the prize money. Work has been reasonably successful in the 4 weeks since I landed back in the Great White North and that's down to one thing: crown ethers.
"What's one of those, then?" I hear you ask. Simply put, it's a series of large macrocycles that bind to lithium, sodium or potassium cations, depending on the size of the ring. The chemists out there will have to stop laughing as I try and make this understandable to the non-chemists. Here's a picture of one; 18-crown-6 refers to the fact it has 18 atoms in the ring, 6 of them oxygen. I hope you can see the crown shape.
It makes the potassium salt so much more soluble, into solvents it has no right to dissolve in otherwise. And for the potassium salts I have been making (I'm sorry to be so vague but the spies from my industrial supervisors are everywhere and I'll be swimming with the fishes if I divulge any more) this has made them so much more agreeable to manipulate, rather than the hopelessly insoluble, evil flyaway solid it was before.
The development of crown ethers in 1967 won Charles Pedersen of Dupont a share in the 1987
Nobel Prize for chemistry in the general area of supramolecular chemistry. And that's a small part of the reason people win Nobel Prizes in chemistry; for their discoveries making the lives of thousands of lab minions like me just a little bit easier decades down the line.
And a postscript. Using my K(18-crown-6) mystery compound, another very successful reaction this afternoon. Experiment ALG261. Yes, the law of nine strikes again. And this time, with two new experiments to write in the lab book, I wrote in the one I wanted to work most. I'm such a cheat sometimes.
