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.

Over the last century, benzene has been a well-studied chemical, with some acute and chronic exposures being directly associated with observed hematologic effects in humans and animals. Chronic heavy exposures to benzene have also been associated with acute myelogenous leukemia

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 acute cardiorespiratory effects of air quality among children living in areas with considerable heavy industry have not been well investigated. We conducted a panel study of children with asthma living in proximity to an industrial complex housing two refineries

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

Benzene causes acute myeloid leukemia and probably other hematological malignancies. As benzene also causes hematotoxicity even in workers exposed to levels below the US permissible occupational exposure limit of 1 part per million, further assessment of the health risks associated
