You may think that concentrating urine on large scale is just for alchemists in the 17th century... well, it's not.

Have a look at this lovely paper.

In order to isolate the so-called Urinod they concentrated a lot of urine.Unfortunately they do not tell how they obtained the urine.

I'm very pleased that I do not have to reproduce their experiment.

And I am very happy that I didn't work in that lab at that time.

After fifteen months they were just unable to smell anymore I think.

And what is this Urinod that makes our urine smell?

I can't believe it... and I'm not the only one.

1000 liters sounds unbelievably traumatic...won't (a) probably isomerize to the more stable alpha-beta unsaturated ketone?
i find it hard to believe too.

My students complain about the stench of isocyanides - this sounds worse. Glad I found your blog!
