| Abstract: | Ionone was synthesized from Litsea cubeba oil and lemen oil,and condition of condensation,cyclization and purification of product was studied.The transformation rate of citral was more than 99% and the yield was 95% in the reaction of citral with acetone.The transformation rate was more than 98% and the yield was 90% in the cyclization of pseudoionone,with 95% of total ketones,among which α-ionone accounts for 80%. |
