中文摘要： 针对目前松香/松节油酸催化深加工过程中均相、非均相催化工艺各自存在的问题和不足，兼顾反应的有效性和分离的简便性，将具有高效催化和自分离双功能的杂多类离子液体有机-无机杂化催化材料用于松香聚合、松节油（α-蒎烯）聚合和直接酯化反应中。通过对新型催化材料的结构设计、合成和性能研究，明确其阴、阳离子各组成部分对其酸性、熔点、溶解性能等起调变作用的根本原因及协同效果，揭示构效关系规律；充分研究新型催化材料在上述反应中的催化和分离性能，明确溶剂-催化剂-反应体系之间的对应匹配关系。利用该类材料兼具杂多化合物与离子液体性能的特征，构建实现高温高效均相反应，低温重结晶分离的催化自分离体系，为松香聚合、α-蒎烯聚合和酯化反应的高附加值产品定向制备提供高效新途径，并为其他酸催化反应体系的反应-分离一体化研究提供理论借鉴。

英文摘要： Enough attention will be given to overcome the drawbacks consisting in both homogeneous and heterogeneous acid catalytic deep processing of rosin/turpentine. Accordingly, the effectiveness of chemical reactions and the separated simplicity of reaction mixtures will be taken into account at the same time. Hereby, heteropoly ionic liquids organic-inorganic hybrid materials(HPILs) with efficient catalysis and self-seperation potentialities will be empolyed into the polymerization of rosin/turpentine(α-pinene) and the esterification of α-pinene to overcome the defects in the present process. Investigation for the structure-performance relationship laws of HPILs will be carried out via the study of their acidities, melting points and solubilities. Moreover, the interreaction of solvent-catalyst-reaction system in the new catalytic process will be studied. Since HPILs possess the properties of both heteropoly compounds and ionic liquids, efficient homogeneous reaction at reaction temperature, recrystallized self-seperation at room temperaturecatalytic systems will be exploited for the directed preparation of objected products. As a result, this project will offer a novel effective path for the preparation of polymerized rosin, terpene resin and terpinyl acetate, as well as, some theoretical references for other acid catalytic integrated reaction and separation technology.
