Abstract
PURPOSE: To prepare the high purity titled compound usable as perfumery, etc. without purification, suppressing byproduction of isomers, by the partial hydrogenation of 3-hexen-1-ol in the presence of a Pd catalyst and a specific ratio, based on the catalyst, of a quinoline, at a specific temperature.
CONSTITUTION: cis-3-Hexen-1-ol is prepared by the partial hydrogenation of 3- hexen-1-ol in the presence of a Pd catalyst and a quinoline to prevent the excessive hydrogenation. The weight ratio of quiniline to Pd metal in the catalyst is 20W60, pref. 25W40, and the reaction temperature is -10W+50°C, pref. 0W30°C. The high purity objective compound (≥99% purity) containing ≤0.2% heean-1-ol and ≤0.7% trans-3-hexen-1-ol is obtained almost quantitatively from 3-hexenol of about 95% purity.
