苯二酚的开发与生产进展

Development and Manufacture Progress of Dihydroxybenzene

介绍了邻、对苯二酚的主要用途、市场需求、生产工艺。重点介绍了苯酚羟基化法合成邻、对苯二酚的先进工艺及其催化剂的开发进展。指出国内外对苯酚羟基化法合成邻、对苯二酚的催化剂研究较多,国内自主开发的催化剂性能优越、成本低廉,并成功进行了工业化。

The main application, market requirement, production process and development process of o- Dihydroxybenzene and p-Dihydroxybenzene were introduced. The preparation technics and refine technics of catechol and hydroquinone from hydroxylation of phenol were emphasized. It was indicated that there were lots of the research of the catalyst interiorly and overseas. While the independent catalyst developed has predominant performance and lower cost, it was applied industrialization triumphantly.
