摘要(Abstract)：

以自制酸改性膨润土负载ZnCl2为催化剂,采用傅里叶红外光谱(FT-IR)和气相色谱-质谱联用(GC-MS)技术对松节油直接催化异构-歧化液相反应进行研究。FT-IR分析表明,在反应产物谱图中蒎烯吸收峰3023 cm-1、1653 cm-1和3067 cm-1消失,苯环的骨架吸收峰1645 cm-1和1456 cm-1、异丙基的特征峰1384 cm-1和1364 cm-1及对位双取代苯的吸收峰814 cm-1强度增大,说明松节油中蒎烯已完全反应,主要产物为对伞花烃;GC-MS分析共分离出42个峰,鉴定出38个化合物,其中主要产物为对伞花烃、3-对孟烯和1-对孟烯,其质量分数分别为60.35%、10.28%和6.59%,蒎烯的转化率为100%,对伞花烃收率为68.10%;对酸改性膨润土负载ZnCl2催化松节油直接异构-歧化液相反应过程进行了探讨,结果表明原料中双环单萜烯发生了开环异构、重排和歧化主反应,同时倍半萜烯和双环单萜烯存在水合、脱氢、脱水和裂解等副反应,获得了酸改性膨润土负载ZnCl2催化松节油异构-歧化复杂反应网络图。
