考察了负载Cr3+和Fe3+的斜发沸石对α-蒎烯液相异构化反应的催化性能，发现主要产物为榄烯和柠檬烯。0.7Fe-CL催化剂比Raw-CL和0.4Cr-CL催化剂具有更好的汽油选择性。在原料斜发沸石上，柠檬烯和其他异构体的比例接近65%，0.7Fe-CL的比例接近15%，0.4Cr-CL的比例接近56%。实验结果还表明，随着反应时间的延长，0.7Fe-CL催化剂在428K时的反应选择性可达72%左右。(C)2012年韩国工业和工程化学学会。爱思唯尔出版，版权所有。
The catalytic properties of the Cr3+- and Fe3+-loaded clinoptilolites were screened in the liquid-phase isomerization of alpha-pinene and the major products were found to be camphene and limonene. Selectivity to camphene was superior for the 0.7Fe-CL catalyst than those observed for the Raw-CL and 0.4Cr-CL catalyst. Over raw clinoptilolite, the proportion of limonene and other isomers reached similar to 65% while it was similar to 15% with 0.7Fe-CL and similar to 56% with 0.4Cr-CL. The results also show that the selectivity to camphene increases with increasing reaction time reaching up to about similar to 72% at 428 K over 0.7Fe-CL catalyst.
