摘要
首次将ＳＯ４２－／ＴｉＯ２固体超强酸用于催化合成萜烯－马来酸酐加成物，确定了催化剂制备及萜烯－马来酸酐加成物合成的适宜工艺条件：ｃ（Ｈ２ＳＯ４）＝０．１０～０．２５ｍｏｌ／Ｌ，焙烧温度５００～５５０℃，焙烧时间３ｈ，催化剂用量为马来酸酐质量的１０％，马来酸酐与松节油的摩尔比１／１．８～１／２．２，反应温度１３０～１５０℃，反应时间２．５～３．０ｈ。用ＦＴ－ＩＲ、ＴＧ－ＤＳＣ及ＸＲＤ等技术研究了催化剂的结构与催化性能的关系。
The solid super acid SO 4 2- /TiO 2 was first used in catalytic synthesis of terpinene-maleic anhydride adduct(TMA).The suitable conditions of preparation of the catalyst and synthesis of TMA were obtained:concentration of H 2SO 4=0.10～0.25mol/L,calcination temperature=500～550℃,calcination time=3h and the amount of catalyst=10% of maleic anhydride,molar ratio of maleic anhydride to turpentine=1/1.8～1/2.2,reaction temperature=130～150℃,reaction time=2.5～3.0h.The relation between activity and structure of SO 4 2- /TiO 2 catalyst was studied by FT-IR,TG-DSC and XRD.
