Continuous processing in the microreactor represents a novel way for the safe and expedient conduct of high energetic nitration. Apart from handling benefits,nitration in microreactors proceed under precisely controlled conditions providing improved yields and selectivity. This paper studied the nitration of toluene in the microglass reactor using concentrated nitric acid as the nitrating agent and SO3H-functional ionic liquids, Lanthanide(iii) trifluoroacetate as recyclable catalysts. We described a mild, efficient process for the nitration of toluene.
