摘　　要：根据量子化学理论与有机化学理论,应用Gaussian09软件模拟了煤-CH2-官能团氧化自燃生成水、一氧化碳化学反应过程,选用B3LYP/6-311G方法,对过程中的每一步化学反应进行优化与计算,搜寻每一个可能存在的过渡态,并进行了反应路径(IRC)8计算,确认所得的每一个过渡态的真实性。最后根据分子轨道理论,进行了电荷密度计算,通过加入硫元素发现,硫元素提高了-CH2-的氧化活性。According to the theories of quantum chemistry and organic chemistry,Gaussian09 software was used to simulate the chemical reaction process of coal -CH2- functional oxidative auto-ignition water generation and carbon monoxide.The B3LYP/6-311G method was used to optimize and calculate the chemical reaction in each step of the process.Search for each possible transition state and perform a intrinsic reaction path(IRC)calculation to confirm the authenticity of each transition state obtained.Finally,according to the molecular orbital theory,the charge density calculation was carried out.It was found that the sulfur element increased the oxidation activity of -CH2- by adding sulfur.
