These crystals formed from an unsuccessful reaction where I got back the compound what I started from. However, they still look great!
I collected the best picture from crystals from my blog and published them at Béhance, check it out: Béhance

I think it might have made *some* HCl, but it still made some calcium sulfate when mixed with Ca(OH)2. It also turned the pink-red dye
yellow. I must have chlorinated the dye, lol. |
How do you make HCl with sulfuric acid and calcium carbonate? There's not a single atom of chlorine in that entire reaction!
Also, can't you just buy some decent HCl at your local hardware store? They have it near the pool stuff usually, and it's a lot easier than making it,
unless of course you're just trying to for the fun of it.

Raw eugenol. Distilled from 24 gms whole cloves. Still surprising me that some of these organics are denser than water.

LOL, oops, meant CaCl2.......
Edit: And yea, just for fun. If I can make it, it's more rewarding then buying it, even if it isn't better quality stuff.

Very nice picture Mailinmypocket!
Do you have or know any practical use for bromo-caffeine? I have a lot of caffeine and no practical use for it, and the means to make the bromo
variant out of it.
I found it promotes aldoximes to nitriles (Sigma), but nothing really comes to mind still.
Do you have any means to test the conversion of the caffeine? (assuming you started from caffeine).

No, I got a nifty little 125ml pyrex sep funnel yesterday in a gift box---and had about 60ml of diethyl ether squirreled away. Extracted it from "el
cheapo" kroger artificial vanilla flavoring. Ethylvanillin was listed as the flavorant. It's weird cause it smells kind of "peppery" to me.

Thank you 
As far as making 8-bromocaffeine I dont have any practical uses for it. Mainly I was just desperate to do something with the 100g of caffeine powder I
have had kicking around for years. For checking purity I will depend on the m.p. - I have recrystallized the product from ethanol and am waiting on
the beautiful crystals to dry and will do a mp on it afterwards to see what the outcome was.
I got the procedure from this document:

I apologize for not saying it as well when I first saw it, but that is a very nice picture.
This might be an interesting project that could use your 8-bromocaffeine.

I started to specifically mention Windows, in the event someone downloaded and couldn't open, they would have those instructions. I am at work and
software engineer by trade. I am currently running Windows 7 and a headless VM of CentOS, so I am using Windows to view the PDFs at this time. At
home, it's back to the MBP.
