| Abstract: | 2-Ethylhexyl p-methoxy cinnamate was synthesized by Knoevenagel condensation and transes- terification.The maximum yield of ethyl p-methoxy cinnamate was 83.7% from p-methoxybenzaldehyde and diethyl malomate by Knoevenagel condensation with the catalysis of L-proline/potassium phosphate.The yield of 2-ethylhexyl p-methoxy cinnamate was 92.3% from ethyl p-methoxy cinnamate and 2-ethylhexanol by trans- esterification with the catalysis of TsOH. |
