摘　　要：The influencing factors for liquid phase catalytic oxidation of mine gas to methanol(in form of CH3COOCH3) are studied using the self-established experimental apparatus. The results show that CH3COOCH3(target product) is obtained by using CH3COOH as reaction solvent, and the yield of target product increases with the increasing of reaction temperature, gas pressure and reaction time. In the mine gas-Pd(OAc)2-CH3COOH system, the yield of CH3COOCH3 increases with the increasing of addition of Pd(OAc)2 which is redox catalyst for mine gas conversion. The yield of CH3COOCH3 will be greatly improved by composite additional oxidant which is obtained by equimolar mix of p-benzoquinone with NO2.The influencing factors for liquid phase catalytic oxidation of mine gas to methanol （in form of CHaCOOCH3） are studied using the self-established experimental apparatus.
