摘要
研究了α-蒎烯在Lewis酸复合催化剂AlCl<sub>3</sub>-Cat Ⅱ作用下聚合反应过程中的变化和聚合反应机理.GC、GC-MS、IR、UV和<sup>1</sup>H NMR等实验结果表明:在α-蒎烯的聚合反应过程中伴有异构反应,并生成了挂异莰烷、冰片基氯、对伞花烃、莰烯、1,4,(3)-对(艹孟)二烯、α-水芹烯和一个分子量为172的未知成分;提出了α-蒎烯是通过(?)和(?)两种正碳离子(其比例为76:24)参与聚合的反应机理.
The change of α-pinene during polymerization reaction process in the presence of Lewis acid complex catalyst AlCl3-Cat II and the polymerization reaction mechanism were studied. It was found by GC,GC-MS,IR,UV and 1H NMR,that the polymerization reaction of α-pinene was accompanied by isomerization reaction and seven constituents, namely: isocamphane, bornyl chloride, para-cymene, camphene, para-mentha-1,4(8)-diene,α-phellandrene and an unidentified component (MW 172) were produced. The reaction was suggested to be carried out through two kinds of carbon cations, namely and
at ratio 76 : 24.
