Abstract
A method of reacting an aromatic compound with an immiscible reacting agent involves the passage of the reactant along a flow path having a width of from 10 to 1000 µm in such a way that essentially laminar flow of the reactant takes place. Reaction takes place across the interface between the phases and without substantial mixing of the unreacted aromatic compound and the reacting agents. A
preferred reaction is the nitration reaction which involves reaction of a first phase comprising an organic aromatic compound on a second phase comprising a nitrating agent to produce two new phases of different chemical composition to the starting phases. The aqueous and organic phases produced are ideally separated such that minimum contamination occurs. Other examples of this type of reaction include the sulphonation of an aromatic compound using sulphuric acid as the sulphonating agent. The aromatic compound is slowly consumed in the reaction yielding a single aqueous phase.
