Europium chloride formation without chlorine gas (I'm lazy)
I have somewhat of a stupid question which I imagine I could answer with about 5 minutes of research, but I'd like to ask the group for their opinion, nonetheless. I'm working on the formation of a Europium based vitamin/coordination-compound. Europium (for those who aren't familiar), reacts very quickly with air AND water, and therefore my previous projects with powdered metallic Europium have been done in a dry box of Argon. But for my current biochemical project, I would like to start with EuCl3 (just a preference, I can get it to work other ways as well by stabbing in the dark a few times).
I'm lazy, and don't want to go through the trouble of buying chlorine gas. I've spent enough money on my Argon/Nitrogen/Oxygen, and their respective tanks. So my initial thought was "Oh, I'll just submerse the sample into a chlorinated solution...BUT WAIT! It will react with the water, ruining the sample". My question is: how would you suggest I expose the Europium to chlorine for the formation of EuCl3 WITHOUT the use of aqueous solution or me having to buy pure chlorine gas? Thank you for your input.
PS: I'm also looking for a supplier of dimethylglyoxime and, of course, pyridine. If anyone wants to get rid of like 100mL / 30grams (small quantities, basically), I'll take it off your hands. Or if you can recommend a supplier, even through Ebay or whatnot, that'd help me out a bunch. Thanks again.
