摘　　要： 概述了苯胺氧化法、对二异丙苯过氧化法、双酚A法和苯酚羟基化法等对苯二酚的生产方法,指出苯酚羟基化法由于产品质量好、无污染等优点,将具有良好的发展前景。分析比较了其催化剂——无机酸、无机盐、分子筛、杂多化合物和复合金属氧化物等的性能与特点,认为铁基复合氧化物价格低廉、催化效果好是今后工艺开发的重点。介绍了焦油的形成和脱除及综合利用、催化剂与其相应反应器的开发、以及连续串联搅拌釜反应器能使铁基复合氧化物催化剂保持较高的活性等研究进展。 Production techniques of hydroquinone, such as oxidation of aniline, peroxidation of p-diisopropylbenzene, decomposition of bisphenol A and hydroxylation of phenol were reviewed. Hydroxylation of phenol showed good prospect because of its advantages of good product quality and no pollution. The properties and characteristics of these catalysts including inorganic acids, inorganic salts, molecular sieves, heteropoly compounds and composite metal oxides were analyzed and compared It was found that iron-based composite catalyst represented the trends of development because of its low price and good properties. The research progress of the formation, removal and comprehensive utilization of tar, the development of reactors of different catalysts and high activity iron-based composite catalyst in continuous stirred tank reactor were introduced.
