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.

David Galbraith et al.
Critical reviews in toxicology, 40 Suppl 2, 1-46 (2010-10-14)
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
Jelle Vlaanderen et al.
Environmental health perspectives, 119(2), 159-167 (2010-10-01)
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
Cliona M McHale et al.
Carcinogenesis, 33(2), 240-252 (2011-12-15)
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

Environmental research, 132, 38-45 (2014-04-20)
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

Abstract A framework of "Common Criteria" (i.e. a series of questions) has been developed to inform the use and evaluation of biomonitoring data in the context of human exposure and risk assessment. The data-rich chemical benzene was selected for use
