Synthetic polymers constitute one of the main carbon-containing wastes generated nowadays. In this study, combined hydrothermal liquefaction (co-HTL) is evaluated for 1:1 mixtures of Miscanthus giganteus and different synthetic polymers-including poly-acrylonitrile-butadiene-styrene (ABS), bisphenol-A-based epoxy resin, high-d. polyethylene (HDPE), low-d. polyethylene (LDPE), polyamide 6 (PA6), polyamide 6/6 (PA66), poly(ethylene terephthalate) (PET), polycarbonate (PC), polypropylene (PP), polystyrene (PS), and polyurethane foam (PUR)-using batch HTL at 350°C. Based on oil yields and composition, a comprehensive discussion of observed interactions is presented. The results show that even though polyolefins do not depolymerize under these conditions, the oil products depict that these materials interact with miscanthus biocrude changing its composition Bisphenol-A-based polymers as PC and epoxy resins both contribute to the formation of monomer-like structures in the biocrude. PET increases the presence of carboxyl groups, while polyamides and PUR increase significantly the oil yield, modifying the biocrude composition toward nitrogen-containing mols. PUR co-HTL was found to increase oil, carbon, and energy yields, leading to process improvement when compared to pure miscanthus processing. HTL of synthetic polymers and biomass can be an opportunity for sustainable recycling of chems. in a synergistic, multipurpose process. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2SDS of cas: 103-16-2).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.SDS of cas: 103-16-2
