Benzene → Nitrobenzene

Participants

Reaction Steps

The reaction Was carried out in the same reactor as that described above in Examples 3 and 4 which are representative of the present invention. Benzene in 7% stoichiometric excess is metered into a nitrating acid consisting of 2.3 wt. % of nitric acid, 68.0 wt. % of sulfuric acid and 29.7 wt. % of water. The amount of benzene was chosen so as to give a space-time yield of nitrobenzene of 4.3 t/m3h, based on the reactor volume. The mixture obtained was introduced into a reactor at a start temperature of 99.8° C. After 13.4 vol. % of the reaction space, the temperature of the reaction mixture was 113.6° C. The reaction end temperature was 123.6° C.
