Cyclohexylamine


Are there any places that sell cyclohexylamine to individuals. Oddly this is the only chem in the last 2 years that I have had problems sourcing within the last 2 years and I work in my lab almost daily.

Depends on where you live for starters - which country, which region in larger countries.

You might consider making it from cyclohexanone which is easier to find, often being part of the solvents and prepping agents for plastic piping.

How is amine most easily obtained form ketone like cyclohexanone?

I had also considered forming the oxime and reducing but then I will be wasting more expensive reagents on a cheaper one.

I am in the midwest USA.

Why waste hydroxylamine ?

Cyclohexane + H2SO/HNO3 (nitration) -------> 1-nitrocyclohexane , then reduction to cyclohexylamine with Sn/HCl .
It's so simple

Saturated hydrocarbons are much less reactive towards substitution than aromatic hydrocarbons. I doubt it will work unless you give me a reference for that reaction.

That being said, I have seen a paper on vapor-phase nitration of alkanes (aliphatic) with conc. nitric acid at high temperatures.

Cyclohexane + sodium azide -------> cyclohexyl azide ----->(reduction with Zn/NH4Cl) -----> cyclohexylamine , hight yielding 90% in 10 minutes refluxing !!!!!!!!!!!!!!!!!!!!!

Reduction of Azides to Amines or Amides
With Zinc and Ammonium Chloride as Reducing Agent
