| Abstract: | The optimum conditions of the pseudo ionone preparation from the condensation of central with ace- tone catalyzed by D261 - type macrospore strong base Resins was investigated. As the ratio of central to acetone is 1：5 （mol/tool） , the ratio of central to the catalyst is 1：1 （w/w） , the conversion rate of citral could reach to 98.65% at 35℃ within 2h, the selectivity of pseudo-ionone （PS） is 95.03%. |
