制备了用于气相选择性氧化制对叔丁基苯甲醛的催化剂 .通过反应温度、进料浓度、空速、催化剂寿命等条件的考察 ,讨论了影响反应的因素 .结果表明 ,在合适的反应条件下产物对叔丁基苯甲醛选择性可达 80 mol%以上 ,反应物对叔丁基甲苯转化率大于 12 mol%,且催化剂经 36 5 h长时间寿命试验活性仍较稳定 ,无论从工业应用前景角度来看 ,还是在环境保护方面都具有很大意义 . The catalysts for the selective gas-phase oxidation of p-tert-butylbenzaldehyde were prepared.The effects of reaction conditions on the reaction temperature, feed concentration, space velocity and catalyst life were discussed.The results showed that under the appropriate reaction conditions The selectivity to p-tert-butylbenzaldehyde was up to 80 mol% and the conversion of p-tert-butyltoluene was more than 12 mol%. The activity of the catalyst after 36 h was still stable. Application perspective, or in the environmental protection are of great significance.
