Does anyone know where I can find a comprehensive list for the solubility of cyanamide?
I'm in the UK so my library doesn't have access to the NIST database.
I have a tutorial coming up and am worried that the tutor will think that I'm an idiot if I suggest something which is impossible.
Thanks in advance

Solubility in isopropanol > 210 g/L Temp. 20°C
Solubility in acetone > 210 g/L Temp. 20°C
Solubility in methanol > 210 g/L Temp. 20°C
Solubility in ethyl acetate > 210 g/L Temp. 20°C
I managed to find this in a book, but it's neither specific nor comprehensive though all of these would be classed as 'soluble'.
I also note that a dash of acetic acid is added to many reactions to prevent polymerization.

It would be nice if other people could check their (paper) media. Someone has surely tested it in dozens of solvents but being a rather 'mature' reagent, that data may not have become digital.
We are losing a VAST amount of important, basic chemistry from the 1890s to the 1920s in particular, whole books by absolute masters of the art. It's certain that their MUST have been a 'Barry Sharpless' or 'Catherine J. Murphy' figure. also, sadly, a lot of 'Karen Wetterhahn'-like people. Genius, lost to an unknown (or rather unconsidered) physical fact of a reagent.
The best example is that of adding mixed nitrogen oxides to a double-bond. With ethene, you get 2-nitroethyl nitrite. Interesting. 2 people discovered this reaction in the 1890s and interestingly both were dead within a year of discovering it. Reaxys & SciFinder find neither of their work. Credit goes to the Nobel laureate Heinrich Wieland who undoubtedly had their works.
I think we need a section called 'dream reaction'. Mine is for Barry to find a reliable, safe, inexpensive reagent to perform chiral hydroaminations on alkenes. His diol was sheer genius... but I WANT MORE!!! ;-)
