I did not realize that \startchemical took the name of an instance as
argument - I have only used it with key=value, i.e.:
\startchemical[...=...] 

I suppose that it uses some "standard" mechanisms.


\definechemical[benzene] is different. It gets used as:

\startchemical
    \chemical[benzene,...]
\stopchemical


Perhaps there is some inconsistency with respect to ConTeXt syntax here.
