FT‐IR spectroscopic studies on degradation of lac resin – part I: thermal degradation Available to Purchase

Studies the thermal degradation of lac resin by FT‐IR spectroscopic techniques to determine functional group changes occurring in the degradative process. Compares FT‐IR spectra of lac during different stages of thermal degradation; observes no indication of inter‐esterification or dehydration from spectroscopic data, as proposed by earlier workers on the basis of wet chemical methods. Unequivocally concludes that inter‐etherification (dioxolanation) and hydroperoxidation reactions are much more likely to occur during the thermal degradation process.
