Catalytic Kinetics and Mechanism Transformation of Fe(acac)(3) on the Urethane Reaction of 1,2-Propanediol with Phenyl Isocyanate 作者: Yang, PF (Yang, Pengfei)[ 1 ] ; Li, TD (Li, Tianduo)[ 1 ] ; Li, JY (Li, Junying)[ 1 ] 来源出版物: INTERNATIONAL JOURNAL OF CHEMICAL KINETICS 卷: 45 期: 10 页: 623-628 DOI: 10.1002/kin.20798 出版年: OCT 2013 被引频次: 0 (来自 Web of Science) 引用的参考文献: 31 [ 查看 Related Records ] 引证关系图引证关系图 摘要: The urethane reaction of 1,2-propanediol with phenyl isocyanate was investigated with ferric acetylacetonate (Fe(acac)(3)) as a catalyst. In situ Fourier transform infrared spectroscopy was used to monitor the reaction, and catalytic kinetics of Fe(acac)(3) was studied. The reaction rates of both hydroxyl groups were described with a second-order equation, from which the influence of the Fe(acac)(3) concentration and reaction temperature was discussed. It was very surprising that the relationship between 1/C and t became constant when reaction temperature increased, which indicated that there was no reactive distinction between the two hydroxyl groups. Although the phenomenon differed with the variation of temperature, it was unaffected by the Fe(acac)(3) concentration. It was attributed to the transformation of the reaction mechanism with the increase in temperature. Furthermore, activation energy (E-a), enthalpy (Delta H*), and entropy (Delta S*) for the catalyzed reaction were determined from Arrhenius and Eyring equations, which testified to the transformation of the reaction mechanism.
