We screen various acid catalysts (mineral, carboxylic, carbonic acids, zeolites, ionic liquids, and metal salts) for PET hydrolysis.
Post-consumer polyethylene terephthalate (PET) was hydrolyzed in pure water over a wide range of temperatures (190–400 °C) and pressures (1–35 MPa) to produce terephthalic acid (TPA). Solid or molten PET subjected as saturated vapor, superheated liquid, compressed supercritical fluid. The highest TPA yields were observed for the hydrolysis liquid water. Isothermal non-isothermal also explored. Rapidly heating reactor contents at about 5–10 °C/s ("fast" hydrolysis) led high yields, did...
PET non-catalyzed, non-isothermal hydrolysis can produce 94% terephthalic acid (TPA) yield in 75 seconds.
The European Observatory of Wildlife (EOW) as part the ENETWILD project, aims to improve capacity for monitoring wildlife populations, implementing international standards data collection, providing guidance on density estimation, and finally, promote collaborative, open networks develop monitoring, initially focusing terrestrial wild mammals. This report presents estimates species that are widely distributed (wild boar (Sus scrofa), roe deer (Capreolus capreolus), red (Cervus elaphus)) by...
Correction for ‘Acid catalyst screening hydrolysis of post-consumer PET waste and exploration acidolysis’ by Patrícia Pereira et al. , Green Chem. 2024, 26 1964–1974, https://doi.org/10.1039/D3GC03906D.
This study reveals the effects of 23 metal salts on hydrolysis postconsumer poly(ethylene terephthalate) (PET). Isothermal reactions were conducted at 200 °C for 2 h and with a 1/10 (w/w) loading PET water. Terephthalic acid (TPA) yields least 80% obtained indium ytterbium triflates, zinc iodide, potassium sodium carbonates, phosphate, bicarbonate. Without additives, TPA yield was less than 10%, suggesting that these are potential candidates to improve chemical recycling PET. We expect...
