Formation of nitrosamines
I did a little experiment in which I made nitrosamines. I found that the diethylnitrosamine can very easily be isolated as a yellow liquid:

I did not keep the nitrosamine, I discarded it because of its potent carcinogenic properties. Are there any interesting uses of nitrosamines in the
home lab, e.g. for nice experiments, or for making other chemicals? I could not find much info on Google, nearly all hits are about its carcinogenic
properties.

A classic example of mad science. Care to make some dioxins next?

It can be reduced to N,N-diethylhydrazine with zinc amalgam. This hydrazine can be N-alkylated to give interesting N,N,N-trialkylhydrazonium salts.

…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being
unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their
scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)

Dimethylamine can be nitrosated into dimethylnitrosamine ((CH3)2N-N=O) wich after reduction leads to dimethylhydrazine...
Dimethylhydrazinium nitroformiate ((CH3)2N-NH2.HC(NO2)3) would be an interesting energetic salt.
Dimethylhydrazine on its own is used as rocket fuel; it should be able to form complex salts with Cu, Zn, Co, Ni and it may be used to make
dimethylhydrazones with active carbonyls...

One could reduce these nitrosamines to their respective hydrazines but alkylhydrazines are exceedingly toxic and carcinogenic as well.
N-methyl-N-nitrosamides are related compounds that are precursors to diazomethane and are also toxic and mutagenic. The explosive "R-salt" is a
nitrosamine.

I made a few nitrosamines in the past, the most remarkable was the phenyl-methyl-nitrosamine what was made from N-methyl-aniline and nitrous acid. A
slightly yellow oil what formed almost quantitative.
The most interesting part of this compound was that it had a really pleasant odor, reminded me to isovanilline. The bad part is, that it is described
everywhere as a toxic, carcinogen, blablabla, ect. compound and the reduction of it to N-methyl-N-phenyl hydrazine failed with the methods what we
tried out.
I have a blog where I post my pictures from my work: http://labphoto.tumblr.com/
-Pictures from chemistry, check it out(:

I recently had reason to prepare dimethylnitrosamine as part of my experiments into the formation azides from hydrazine and as Woelen observed it is
soluble in water. I tried extracting it with ether but yield was rather poor though after removal of the ether (by leaving in a shallow basin to
evaporate the ether) I did recover a small amount of yellow oil but only about a fifth of what I expected.
