Reaction Steps
After dissolving 24.4 g (0.2 mole) of 4-hydroxy benzaldehyde in 200 ml of ethyl acetate, 21.6 g (0.3 mole) of ethyl vinyl ether and 0.2 ml (2 millimole) of hydrochloric acid were added, and the mixture was stirred overnight at room temperature. Then, after adding Na2CO3 aqueous solution to neutralize, the mixture was separated and the upper layer was washed with water until pH thereof reached 7. After adding MgSO4 to dry, the mixture was filtered, concentrated and dried, and distilled under reduced pressure to obtain EEBA (100–105° C./0.4 mmHg). Amount obtained was 20 g (yield was 50%).
