Fundamentals of keto-hydrazide crosslinking
The fundamentals of the keto-hydrazide reaction werestudied 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.
