摘要： 通过引入竞争反应, 彻底地抑止了以过氧化氢为氧化剂进行的苯和苯酚的羟化反应过程中焦油的产生, 从而使得反应活性和催化剂的使用寿命都显著提高.

关键词: 芳烃的羟化反应, 竞争反应, 抑止焦油

Abstract: It is shown here that, by introduction of competitive reaction, the formation of tar in hydroxylation of aromatics can be completely avoided. As a result, higher catalytic selectivity and longer durability of the catalysts are achieved, compared with those of the conventional process for hydroxylation of phenol and benzene with H2O2.

Key words: Hydroxylation of aromatics, Competitive reaction, Avoidance of tar
