摘　　要：综述了苯酚传统生产工艺的改进及新工艺开发方面的研究进展。异丙苯法是目前世界上最主要的苯酚生产方法,近年来不断地得到改进和完善;甲苯-苯甲酸法由于原料甲苯来源广泛,生产工艺流程较为简单,可根据市场需求调整产品结构,是继异丙苯法之后较为成熟的生产工艺;以N2O,H2O2,O2为氧化剂的苯一步氧化法作为绿色的苯酚合成工艺,其开发应受到重视;以分子筛为催化剂的仲丁基苯法可有效利用C4资源,适合我国国情,应加大开发力度。Manufacturing of phenol and relevant development were reviewed. Cumene process was the most prevalent for commercialized production of phenol, which was significantly improved in recent years. The toluene-benzoic acid process was a relatively mature simple process followed the cumene process due to extensive available toluene source, by which product structure could be easily adjusted according to the demand of market. The advance in novel technologies included direct hydroxylation of benzene to phenol using N2O, H2O2 and O2 as oxidants, and sec-butylbenzene process using zeolite as catalyst. The former was environmental-friendly and could sustain long term development but needed to put in further emphasis. The latter was more suitable to China＇ s situation since it was possible to greatly consume the available byproduct of petrochemical industry, but also needed further development.
