Abstract: A synthesis process of 4-methoxystyrene by NaBH₄ reduction of p-acetanisole and zeolite catalytic dehydration of 1-(4-methoxyphenyl)ethanol was developed. An optimized synthesis process was proposed with vaporization temperature of 270℃,reaction temperature of 280℃,vacuum of -0.09MPa and feed rate of 1mL/min,and with a yield of 85% [based on 1-(4-methoxyphenyl)ethanol] and GC purity of 95%. The product was characterized by IR, ¹H NMR and MS. The synthesis process of 4-methoxystyrene with mild reaction condition,simple control and availability of raw materials would have potential for industrial production.
