Fundamentals of keto-hydrazide crosslinking
The fundamentals of the keto-hydrazide reaction were
studied using model compounds as previously
described. Solutions of 2-heptanone (0.1 M) and octanoic
hydrazide (0.1 M) were prepared in methanol and
aliquots combined. The reaction solutions were
analyzed using Fourier transform IR spectroscopy
(Mattson Research Series), nuclear magnetic resonance
spectroscopy (Jeol EX90), and gas chromatography
mass spectroscopy (Thermo Finnigan Trace) in
order to establish the nature of the reaction product
and the catalytic influence of pH.
