| Abstract: | 2-Ethylhexyl p methoxycinnamate was synthesized with phase transfer catalyst polyethylene glycol (PEG). The result showed that the catalytic effect of PEG400 was the best and the yield reached 75.2% .The b.p,Ms ,IR and HNMR spectral data indicated that the synthetic product was 2 ethylhexyl p methoxycinnamate. |
