摘要
文章综述了邻苯基苯酚的现有生产技术,重点介绍了合成法中环己酮缩合脱氢工艺的技术现状,指出提高催化剂脱氢活性和总体收率,增强反应选择性和催化剂稳定性是环己酮缩合脱氢工艺工业化应用的关键。文章分析了国内外生产情况,介绍了国内主要生产装置,详述了邻苯基苯酚广泛的市场用途,提出了我国要发展邻苯基苯酚工业,开发选择性高、活性时间长的催化剂是发展方向。
The paper summarized the manufacture technology of o-phenylphenol in existence, emphasized the technical actuality of cyclohexanone dehydrogenate condensation process in synthetic method. To improve dehydrogenate catalyst activity and the overall yield, enhancing reaction selectivity and stability of the catalyst is the sticking point of industrial application in cyclohexanone dehydrogenate condensation process. The paper analyzed the manufactural situation at home and abroad, introduced domestic major installations, summarized the broad application of o-phenylphenol. It was concluded that to develop the high selectivity, long-time activity catalyst was the way to expand China＇s o-phenylphenol industry.
