Abstract
A study of the slow hydrolysis of labile acetal groups by low concentrations of lactic acid to release the active molecules is reported. A prototype molecule containing cyclic acetal groups, dimethyl‐2,3‐O‐benzylidene‐L‐tartrate (DMTAc) and the same molecule incorporated as a pendant group in a polyamide were studied for their hydrolysis by low concentrations of lactic acid. The release of benzaldehyde during slow hydrolysis is monitored by UV‐vis and 1H‐NMR spectroscopy. This study is very useful to ultimately design and synthesize a polymer with covalently bound insecticidal/anti‐microbial/anti‐fungal materials for the development of controlled release formulations.
