Nitrations in aqueous methanesulphonic acid are shown by the steep acidity dependence of the rate constants, the identification of a kinetic form zeroth-order in the concentration of the aromatic, and the existence of a limiting rate constant identified as the encounter rate constant, most probably to involve the nitronium ion.
