Abstract

C2H5OH is one of important renewable fuels. The mechanism for the C2H5OH + HCO reaction has been investigated by a potential energy surface calculation at the B3LYP/aug-cc-pVTZ (optimization) and CCSD(T)/cc-pVTZ (single-point) levels. Our results show that the HCO free radical can abstract the H atoms in the OH group giving CH3CH2O + CH2O or in the CH2 group giving CH3CHOH + CH2O. The rate constant results by TST calculations considering tunneling corrections show that the second pathway is dominate in all the calculation temperature range of 300-2000K.
