Application

  • Synthesis of poly (styrene oxide) with different molecular weights using tin catalysts: This study explores the ring-opening polymerization of styrene oxide using tin catalysts to produce homopolymers with varying molecular weights (Kayan, 2015).
  • Electrogenerated BF3 from tetrafluoroborate-based ionic liquids: theoretical and experimental studies towards selective styrene oxide isomerization: Research on using electrogenerated BF3 to selectively isomerize styrene oxide, highlighting theoretical and experimental insights (Bortolami et al., 2021).
  • Selective conversion of styrene oxide to 2-phenylethanol in cascade reactions over non-noble metal catalysts: This paper investigates the catalytic conversion of styrene oxide to 2-phenylethanol using non-noble metal catalysts (Sasu et al., 2016).
  • Laboratory blueprints for interstellar searches of aromatic chiral molecules: rotational signatures of styrene oxide: Study of the rotational spectra of styrene oxide for potential detection in interstellar space (Stahl et al., 2020).
