background solvents such as benzene and toluene are commonly used in tire manufacturing, and significant occupational exposure to these chemicals adversely affects the health of workers. in biological monitoring, a complementary method for personal monitoring, the internal absorbed dose is measured and individual, environmental, and exposure differences are taken into consideration. conclusions...

BTX compounds (Benzene, toluene and xylenes) are the main pollutants in air and fuels. Recent environmental legislations are limited the amount of these materials specially the amount of benzene in gasoline due to its carcinogen effects on health. In this research, the BTX hydrogenation was carried out using nanoparticles of Co supported on MWCNTs (multiwall carbon nanotubes) and AC (activated ...

Abstract Complex [( DIPeP BDI)Ca] 2 (C 6 H ), with a C 2− dianion bridging two Ca 2+ ions, reacts benzene to yield (biphenyl) biphenyl ( BDI=HC[C(Me)N‐DIPeP] ; DIPeP=2,6‐CH(Et) ‐phenyl). The complex was also prepared by reacting ) or reduction of BDI)CaI] KC 8 in presence biphenyl. Benzene‐benzene coupling observed when the deep purple product ball‐milling DIPP BDI)CaI(THF)] K/KI extracted (DIP...

The benzene–ethene and parallel-displaced (PD) benzene–benzene dimers are the most fundamental systems involving π–π stacking interactions. Several high-level ab initio investigations calculated binding energies of these using coupled-cluster with singles, doubles, quasi-perturbative triple excitations [CCSD(T)] method at complete basis set [CBS] limit various approaches such as reduced virtual...

Temperature dependences of the free energy (F), entropy (S) and heat capacity (C_v) are calculated (P=0) for organic compounds (solid benzene, naphthalene anthracene) by using quasiharmonic approximation. Contributions to those thermodynamic functions due Raman frequencies lattice modes benzene), librational (naphthalene), phonons vibrons (anthracene) taken into account in our calculations. We ...
