| Abstract: | In this paper 2-cyclopentylidene-1-cyclopentanone was synthesized with solid superbase as the catalyst,cyclopentanone as sole raw material,cyclohexane,benzene or petroleum(60~90℃)ether as water-carrying agent respectively.The influence factors of catalyst amount,solvent and reaction temperature on the yield of the product were examined.Then the optimum conditions of self-condensation reaction were obtained:reaction time was 8h,catalyst amount was 13 wt%of cyclopentanone and cyclohexane as watercarrying agent,and the yield of 2-cyclopentylidene-1-cyclopentanone could reach up to 90.8%. |
