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).

Critical reviews in toxicology, 24 Suppl, S49-S55 (1994-01-01)
Eleven long-term toxicity studies were reviewed on styrene and five on styrene oxide in an effort to evaluate the potential carcinogenic activity of these chemicals in animals. The styrene studies included inhalation exposure (rats, mice, guinea pigs, and rabbits), intragastric

The application of whole cells as biocatalysts is often limited by the toxicity of organic solvents, which constitute interesting substrates/products or can be used as a second phase for in situ product removal and as tools to control multistep biocatalysis.
D H Phillips et al.
Critical reviews in toxicology, 24 Suppl, S35-S46 (1994-01-01)
Styrene is metabolized to styrene oxide, a direct-acting mutagen and carcinogen. Styrene oxide reacts with DNA mainly at the N-7 position in guanine, but also at other sites and with other bases. Substitution occurs at both the alpha- and beta-positions

Regulatory toxicology and pharmacology : RTP, 62(1), 214-220 (2011-11-02)
Styrene induces lung tumors in mice but not in rats. Although metabolism of styrene to 7,8-styrene oxide (SO) by CYP2E1 has been suggested as a mediator of styrene toxicity, lung toxicity is not attenuated in CYP2E1 knockout mice. However, styrene
