Chemically recyclable polyester thermosets from activated adipic acid and renewable polyols
ChemSusChem, Accepted Article.This study outlines a method for producing chemically recyclable crosslinked polyesters using renewable polyols – glycerol and sorbitol – combined with adipic acid (AA), which is transformed/activated into a polyanhydride mixture prior to use. A three‐step procedure was designed: i) an acid‐catalyzed reaction of AA with non‐toxic isopropenyl acetate or

Drug Testing and Analysis, EarlyView.A LC–MS/MS method has been validated for analysis of semi‐synthetic cannabinoids (SSC) and selected phytocannabinoids in seizures. Further SSC‐derivatives were implemented into the method for qualitative detection. The methodology was applied to a sample collective (n = 80) including cannabis flowers, resins, edibles and vape liquids.
