Abstract
The present invention belongs to the technical field of fine chemical engineering, and specifically relates to a method for producing diphenylamine. The method comprises: in the presence of an olefin, allowing aniline to come into contact with a catalyst, and performing a condensation reaction, wherein there are 2-4 carbon atoms in the olefin. By means of introducing an olefin into a reaction system, the method for producing diphenylamine provided in the present invention can effectively improve the conversion rate of aniline and the stability of the reaction, where the conversion rate of aniline can reach a maximum of 40.2 mol% while maintaining relatively high selectivity.
