Abstract
An investigation was made on the addition reaction of camphene [1], tricyclene [2], 2-carene [3] and 3-carene [4] with alcohols (C4 approximately C4) in the presence of synthetic zeolites.
In methanol with HSZ-330 HUA synthetic zeolite at 70-degrees-C, the addition of [1] gave 1,7, 7 trimethyl-2-methoxybicyclo[2.2.1]heptane [5] with high selectivity (97,5% at optimum). In 1-buthanol with HSZ-360 HUA synthetic zeolite, 1,7,7-trimethyl-2-butoxybicyclo[2.2.1] heptane [8] was obtained with high selectivity (high 82%) from [2]. The addition of [3] and [4] gave 8 alkoxy-1-p-menthene compounds as the major products.
These compounds were evaluated on the basis of their odor: [5], [7], [12] emitted an odor that would qualify them for use as flavor materials.
