摘　　要：研究了萘一步催化氧化合成α-萘酚的新方法,选用了有较大孔径的分子筛(FeVPI-5)为催化剂,过氧化氢为氧化剂。重点讨论了溶剂、进料比、催化剂用量、反应时间和反应温度对萘羟基化反应的影响。结果表明:以丙酮为溶剂,n(H2O2):n(C10H8)=1.0,催化剂用量为萘的10%(质量百分比),反应时间10h,反应温度55℃,α-萘酚的最高产率可达20.4%。该法工艺简单、原料易得,而且没有三废,是一种理想的环保方法。A new method of directly producing α- naphthol from naphthalene is studied, iron - substituted aluminophosphate molecular sieve （FeVPI -5 ）is used as catalyst and hydrogen peroxide as oxidant in this method. The effect of solvent, the molar ratio of hydrogen peroxide and naphthalene, the amount of catalyst,reaction time and temperature on hydroxylation of naphthalene are discussed. The experimental results show that： the solvent is acetone, the molar ratio of hydrogen peroxide and naphthalene is 1.0, the amount of catalyst is 10% （ according to the weight of naphthalene）, the reaction time is 10 hours, the reaction temperature is 55 ℃ and the highest ratio of α - naphthalene can reach 20.4 % . So the process of this method is simple and the raw materials can be easily obtained, and it is an ideal nonpolluting method that will not discharge the three wastes.
