Abstract

An apparatus to allow reaction in the liquid phase. The apparatus is a vessel having a baffle. There are openings in the baffle through each of which a liquid passes as a jet. Neighboring openings are sufficiently close to allow impingement of the jets thereby allowing for reaction of the liquids. The invention finds application in reactions where the reactants are immiscible and is particularly suitable in the nitration of aromatic hydrocarbons using mixed acids in aqueous solution. A method of conducting a reaction between at least two reactants in the liquid phase is also provided comprising passing a liquid containing the reactants through a plurality of adjacent spaced openings to create a series of impinging jets.
