萜烯醇酯衍生物的合成、表征及其热裂解行为研究

     

摘要

以不同种类的羧酸和萜烯醇为原料,采用DCC/DMAP偶合法合成7种萜烯醇酯,产率为79.2%~93.5%。此合成方法反应时间短、反应条件温和、节能环保易操作。此外,通过高分辨质谱、13 C NMR、1 H NMR确认了所合成化合物的结构。分别在300℃、600℃和800℃的温度下对肉豆蔻酸橙花酯进行热裂解,应用气质联用仪分析并确定了裂解产物:香茅烯、樟脑萜、月桂烯、β-蒎烯、β-罗勒烯、橙花醇、芳樟醇、香叶醇、肉豆蔻酸乙酯和醛等30多种,裂解产物中多为致香物质,可充分增强卷烟香气,改善吸味。%Seven kinds of terpene ester derivatives were synthesized by the DCC/DMAP coupling method with different kinds of carboxylic acids and terpenols as raw materials. The yields of the target compounds were in the range of 79. 2% ~93. 5%. The synthetic method was comparably simple and had a short reaction time, and the reaction conditions were mild, it also could save energy and protect environment. In addition, the structural characteristics of the synthesized compounds were confirmed by HRMS, 1 H NMR and 13 C NMR. The pyrolysis products which came from thermal degradation behaviour of neryl myristate in the temperature of 300 ℃, 600 ℃ and 800 ℃ were analyzed and determined by GC-MS. The results showed that these products were mostly fragrant substances, can enhance the cigarette aroma and improve the smell of smoke fully.
