Reaction Steps

A mixture of 300 parts of 8,9-limonene oxide, 6 parts of calcium hydroxide and 6 parts of carvacrol was refluxed at 215-230° C. for 2 hours in a three-necked flask equipped agitator, Dean-Stark trap, and temperature probe. After cooling and filtration 290 parts of the mixture containing 30% of unreacted epoxide and 43% 1,8-p-menthadien-10-ol (61% selectivity) was obtained.
