Nitric acid, Nitration, and Nitrate Esters

The kinetics of ion-pair formation in concentrated aqueous NaN03 and of the protolysis of 2.0-14.7 mol liter nitric acid have been studied by Raman line broadening. Rate constants for the individual processes (15) and an equilibrium constant for the dissociation have been estimated, the latter having a value of 8.9 liter mol at 298 K  

0kJmol ), or AS relationship has been established between the Me activity coefficient function and a corrected observed second-order rate constant for nitration of aromatics in concentrated 112804. Ipsonitration of 4-[ N]-02NCeH40H with unlabeled HNO3 has been found to lead to 11% incorporation of the label in the 2-position of the 2,4-(02N)2CeH30H product, accounted for by migration of NO2 in a radical pair (21) for which cidnp evidence was reported [equation (17)]  

Maya and Stedman have studied the decomposition of HN3 in HNO3 and propose the approximate stoichiometry (370 K, 9.18 mol-liter HNO3) in equation (18)  

The solvolysis kinetics data for secondary alkyl nitrates have been used to question current methods of calculating activation heat capacities ACp, a parameter of interest because it has been argued that a major contribution to its sign and magnitude arises from solvation changes during activation.
