General description

Benzene is widely used as a solvent. Its emission from various tropical biomass species has been investigated. GC/MS determination indicated that benzene is one of the major contributor for biomass burning emission factor.[1] Its electronic spectra has been investigated by CNDO method.[2] Microwave spectra of isotopic 1:1 clusters of benzene with water (H2O, D2O and HDO) has been investigated.[3]

Application

Benzene may be employed in the preparation of carbon fibers, via pyrolysis along with hydrogen at about 1100°C.[4] It was used in the preparation of highly conductive molecular junctions. These junctions were fabricated by direct binding of benzene molecules to the Pt electrodes without using anchoring groups.[5]
