Chromatography strategies for the composition determination of bio-based sorbitol azelaic acid ester

Bio-based sorbitol azelaic acid ester (SAAE) is an alternative to the fossil fuel derived polyester polyol for polyurethane production. The quality of SAAE is affected by the composition of sorbitol (SL) and its anhydrides azelate. Unavailability of the standard of these esters renders the compositi...
