Just a larger sized reflux with a homogeneous reaction mixture in it.

Filtering out the product of a diazotation. It has an awesome color due the copper(2+) ions.

Have You seen my portfolio? It’s over here: http://labphoto.tumblr.com/tagged/portfolio

did you do a crossed aldol-catalytic hydrogenation to make the raspberry ketone?

Tue, 21 May 2013 21:35:25 +0200

Yes, exactly. Look up some older posts, and you will see how did it went, from step to step(:

A large amount of freshly prepared and recrystallized rheosmin (also called raspberry ketone). The only problem that is has almost no smell at all, but according to the NMR spectra it is perfectly pure.

We have just made some metallic silver from scrap, approx. 250g with a ~99,99% purity.

It was melted in a ceramic crucible with an oxygene/methane torch, under circa 1h. The silver was liquified under a layer of borax (it prevents the oxidation of the molten silver).

After all have melted we just dropped it in a bucket of water and took out this shiny lump of this beautiful metal.

Should I write it down of you know it? Chemistry is AWESOME!

FIRE IN THE LAB!

Joke, just burning out the acetone from the filtered metallic silver.

Gunk, gunk, gunk and gunk. Dry distillation of furanecarboxylic acid yields furane and CO2, it’s an easy decarboxylation. The problem is that it also produces a massive amount of tarry byproduct.

Distilling something sweet.

This nice reddish color is caused by a little iodine contamination.

An awesome reaction, what behaved as described. The only problem was that my compound disappeared from it. Not in the organic layer and not in the water phase. WHY?

One of my fav pics: refining some palladium from 10% Pd/C. This awesome color is caused by the aqua regia and the palladium ions, I just love it!

Lithium-deuteride and lithium-aluminium-deuteride, a few simple reagents for stable isotope labelled chemistry, where instead of normal hydrogen, deuterium is used.

And also the key reactant for a fusion bomb :D

A few mg of acetylferrocene prepared freshly from ferrocene, currently drying on the rotavap. It looks like metallic crystals at the side of the breaker(:

A small sample of freshly sublimed ferrocene, a metallocene, the first ever discovered sandwich compound.

Anyone needs a hi-res pic? Beware, beautiful crystals could be found on the glass!(:

Dear followers,

This blog have just reached it’s 1000.-th follower! I know, that this is ain’t so much, but since the topic what I post about here is only interesting for a really small percent of the world I think that this is a really nice number(:

Thank you a lot for following/supporting this photo project with your interest, your comments and everything else. It feels awesome, that there is at least 1000 people in the word who has an interest in applied organic chemistry and likes this much this photo project.

Thanks a lot again for everyone!

A reaction after quenching it with some KI3. The carbon-mercury bond breaks, a carbon-iodine bond forms and this red mercury-iodide separates.

Isn’t it pretty?

This pretty yellowish stuff is some highly toxic and hazardous organomercuric reagent what was made in situ from some mercury(II)-acetate and an alkene.

Real, sweet organometallic chemistry(:

Working with micro amounts. The title reaction is a hydrogenation experiment with the Wilkinson caralyst, a pretty expensive rhodium based stuff.

The hydrogen bubbles through the needle into the reaction, hope that it will do something useful.

What test is the best to know that is there any aldehyde present if your tube? The silver mirror test!

A photochemical reactions product wainting for the workup. It has an adorable fluorescent green color, just loving it.
