摘要:

用MINDO/3方法研究了乙酰丙酮的热分解反应,研究结果表明,醇式构型比酮式构型稳定;具有最低能垒的两个反应通道──反应(1)和(2)的活化位垒分别为210.250和225.501 kJ·mol~(-1).

Abstract:

The thermal decomposition of acetylacetone has heen studied with MINDO/3 MO theory. The results obtained show that the enol forms are more stable than the tone forms; the activation energies of the reaction (1) and (2) are 210.250 and 225.501 kJ·mol~(-1), respectively.
