摘　　要：采用磷酸芳基酯催化苯胺与苯酚合成二苯胺的新工艺，探讨了合成反应条件对二苯胺收率的影响规律。在ＨＤ９５－２用量８％，苯胺与苯酚摩尔比２∶１及反应温度３６０℃，反应时间１４ｈ的优化工艺条件下，二苯胺的收率达到５５％以上。A new process has been developed to synthesize diphenylamine from aniline and phenol by catalysis of phosphoric ester and a study of the effect of reaction conditions on the yield of diphenylamine was also conducted.The yield of diphenylamine was above 55% under the optimum reaction condition,i.e.the consumption of HD95 2 was 8%,the molar ratio of aniline to phenol was 2∶1,the temperature was 360℃,and the reaction time was 14h
