合成ゼオライトを触媒とするピナン, 2-および2 (10)- ピネンの熱異性化反応

抄録

The thermo-isomerization of l-cis-pinane (1), 2-pinene (2) and 2 (10)-pinene (3) in the presence of synthetic zeolites (A-3, A-4, A-5, F-9 and TSZ-642) was investigated. Whith TSZ-642 zeolite, dihydromyrcene (5) was obtained with high selec-tivity (high 85%) in all converted products from (1). 4 E/6 Z-Alloocimene (10) and 4 E/6 E-alloo-cimene (11) were obtained from (2) as the main products, amounting to 86% (77:9) of the isom-erization product. Myrcene (12) was obtained from (3) as the main product, amounting to 83% of the isomerization product under the best conditions.
