Procedure
Essentially the same manufacturing setup discussed above for propane nitration is used to nitrate cyclohexane and obtain nitrocyclohexane within product purity specifications. Cyclohexane is nitrated using about 30 weight percent dilute aqueous nitric acid as the nitrating agent at the following process conditions: about 1200 psig reactor pressure, about 220 degrees Celsius reactor temperature, a residence time of about 120 seconds, and a cyclohexane to nitric acid mole ratio of about 2:1. FIG. 3 illustrates an apparatus 300 for synthesizing nitrocyclohexane. A hydrocarbon feedstock 301, comprising cyclohexane, and aqueous nitric acid 302 are introduced into a reactor 303 and react to form a reaction product stream 304. A composition of a typical reaction product stream 304 from the reactor 303 is summarized in Table 3.
