An investigation into the different forms of lac resin using FT‐IR and diffuse reflectance spectroscopy
Abstract
Studies different forms of lac resin, viz. sticklac, seedlac and shellac by FT‐IR spectroscopy. Also compares the FT‐IR and DRIFT spectra of lac obtained from different host trees in an attempt to explain the differences in their physico‐chemical properties. Concludes that all lacs are a structurally similar class of compounds but differ in physico‐chemical behaviour due to minor compositional differences, especially with reference to hydroxylic content, long chain fatty acid content and unsaturation.
