General description

Benzene is a monocyclic aromatic compound used as a solvent in chemical reactions. It is an essential raw material for fuels, rubber and plastics products, detergents, pesticides, and pharmaceuticals.

Application

Benzene can be used as a solvent in the:
  • Heck Reaction of vinyl bromides with styrenes to synthesize functionalized 1,3-dienes.
  • Gallium-catalyzed reductive lactonization of γ-keto acids to γ-lactone derivatives.
  • Anionic polymerization of styrene and 1,3-butadiene in the presence of phosphazene as a base.

Benzene exposure has been associated with increased risk of leukaemia and myelodysplastic syndrome. Existing studies are sparse for other lymphohaematopoietic cancer subtypes, such as myeloproliferative disease (MPD) and the related chronic myeloid leukaemia (CML). We pooled data from three petroleum

The use of occupational cohort studies to assess the association of benzene and lymphoma is complicated by problems with exposure misclassification, outcome classification, and low statistical power. We performed meta-analyses of occupational cohort studies for five different lymphoma categories: Hodgkin
