| Abstract: | The Ionone was synthesized by new catalyst:(1) Citral and acetone took Aldol condensation reaction,using CH3ONa as base catalyst,under conditions of 50～60℃,took reaction for 3.5 hours to produce pseudoionone,the yield was up to 95.3%.(2) Then pseudoionone in phosphoric acid took cyclic-condensation reaction to form Ionone product at 55～65℃,the product Ionone’s content was up to 97.6%,yield was up to 81.5%.The reaction conditions have been analysized and discussed,the Ionone’s IR spectra and NMR Spectra have been characterized and discussed in detail. |
