Die Idee besteht darin, in der Lage zu sein, mit deinen Negativen zu arbeiten und auf zerstrungsfreie Weise zum Ursprung. These findings offer valuable guidance for designing more efficient metal-free protic ionic salts, promoting sustainable PET recycling. Darktable ist ein unglaublich umfassendes Fotobearbeitungsprogramm, mit dem du deine RAW-Bilddateien in einer digitalen Dunkelkammer bearbeiten kannst. The rate-determining step is the nucleophilic attack step, where the Gibbs energy barriers (Δ G ≠) increase in the order of 29.7 kcal mol −1 (HTBD-OAc) 82.4% (HTBD-CH 3CH 2COO) > 80.2% (HTBD-HCOO) > 73.6% (HTBD-CH 3COCOO) > 4.7% (HTBD-NO 3). Furthermore, density functional theory calculations demonstrated that the HTBD cation and anionic ligands work in a cooperative manner in the PET glycolysis reaction, where the ligands abstract a proton from EG to generate EG − and provide a proton to produce the bis(hydroxyalkyl)terephthalate (BHET) product. The proton capture ability of the anionic ligand from EG is positively correlated with the activity of the catalyst, as the generation of EG − was crucial for the chain breaking reaction via nucleophilic attack on the carbonyl group. Darktable is een opensource-raw-fotobewerkingsprogramma, een virtuele lichtbak en donkere. The structure–activity relationships of 1,5,7-triazabicyclodec-5-ene (TBD) based protic ionic salts for polyethylene terephthalate (PET) glycolysis by ethylene glycol (EG) were comprehensively investigated through theoretical prediction and experimental verification. Versie 4.0.0 van Darktable is uitgekomen.
