无机盐调控Raney Ni催化硝基苯类化合物硝基加氢的研究

, 2015
苯胺类化合物(ANs)作为一类重要的有机合成中间体，在精细化工领域占有非常重要的地位。苯胺类化合物主要是由相应的硝基苯类化合物(NBs)还原制得，其中液相催化加氢还原法因其环境友好而成为合成苯胺类化合物的主要方法。金属催化剂是影响液相催化加氢效率的关键因素，其中Raney Ni催化剂，因其价格较贵金属催化剂便宜，而更适合实际工业化生产。但是Raney Ni的催化活性有待进一步提高，而且硝基苯类化合物加氢过程中中间产物的积累影响加氢反应的进程，有待改善。 针对以上问题，本文选用Raney Ni为催化剂 ...

β－苯乙醇的制备方法

, 2004
本发明公开了一种由苯和环氧乙烷在无水三氯化铝催化作用下，制备β-苯乙醇的制备方法，在制备过程中采用定量水解方法得到β-苯乙醇。与现有的烷基化方法相比，苯消耗降低约50％，并可回收副产氯乙醇和聚合氯化铝，消除了含苯酸性废水污染和设备腐蚀 ...

一种用于由多烷基苯和苯生产单烷基苯用的改性沸石催化剂及其制备方法

, 2002
一种用于由多烷基苯和苯生产单烷基苯用的催化剂，由SiO2/Al2O3摩尔比为8～20的HY沸石和惰性组分构成，其中Y沸石重量范围为40～90％，其余为惰性组分和0.01～5％(重量)的选自P、碱金属和碱土金属元素的一种或一种以上的助剂元素。该催化剂用于多乙基苯和苯液相烷基转移过程生产乙苯，多乙基苯的转化率大于60％，生成乙苯的选择性大于99％，乙苯中二甲苯含量＜120ppm ...
