PROBLEM TO BE SOLVED: To provide a method for continuously producing nitrobenzene which on the one hand affords a high space-time yield, and on the other hand continues to assure the required product quality. SOLUTION: The method for continuously producing nitrobenzene includes nitrating benzene with a mixed acid that contains at least 3.0 mass% of nitric acid and at least 67.0 mass% of sulfuric acid, in a reaction space in which the start temperature of the reaction is above 100.0°C but below 102.0°C. In addition, it is necessary that the above benzene and the above mixed acid are dispersed with one another several times. COPYRIGHT: (C)2010,JPO&INPIT |
