本文研究了氢型丝光沸石催化愈创木酚(1)与莰烯(2)的选择性烷基化反应. 该烷基化反应产物萜基愈创木酚(3～6)中含5-异莰基愈创木酚(3a)25.0%, 经氢化, 氢解得萜基环己醇混合物, 含人造檀香主要成份反式-3-异莰基环己醇(7a)23.0%. 通过IR, ^1H NMR 和MS鉴定了烷基化产物色谱图中的5个主要化合物.

The selective alkylation reaction of guaiacol (1) with camphene (2) over H-Mordenite has been studied, through which the content of 5-isocamphylguaiacol (3a) among the alkylation products terpenylguaiacols (3～6) has been raised to about 25.0% . The subsequent hydrogenation and hydrogenolysis of the obtained alkylation products give a mixture of terpenylcyclohexanols containing 23.0% of trans-3-isocamphylcyclohexanol which is the essential constituent of "Santalydol". Five main peaks on gas chromatography of the alkylation products have been identified by IR, ^1H NMR and MS .

Key words: SELECTIVITY, ALKYLATION, MORDENITE, CAMPHENE, GUAIACOL
