Extractive acid used as the continuous phase, the separation ofm-chloroaniline and p-chloroaniline is carried out by continuous counter-current dissociation extraction in a filling power equipment. 以萃取酸为连续相,应用填料塔设备对间氯苯胺及对氯苯胺混合物进行连续解离萃取以提纯间氯苯胺。
The separation ofm-chloroaniline and p-chloroaniline was carried out by countercurrent dissociation extraction ( CDE). 逆流解离萃取通过套用萃取酸分离间氯苯胺及对氯苯胺。
Up to date, p-chloroaniline was reported to be biodegraded only through ortho-or modified ortho-cleavage pathway. 迄今为止的研究报道表明,对氯苯胺的生物降解只能以邻位途径或修饰邻位途径进行。
The extremely high selectivity to p-chloroaniline was due to the high activity of nanon Ru on carbon as well as the characteristic surface basic properties of the Ru/ C catalyst. 催化剂的高活性和高选择性与纳米Ru在活性炭上的高分散度及催化剂的表面碱性有关。
