The reversible sulfonation at the α-position of β-(p-chloroanilino) acrolein (V) in sulfuric acid at various concentrations was studied kinetically. The rate constants of cyclodehydration of β-(p-toluidino) acrolein (I) with reversible sulfonation at the α-position were evaluated by non-linear least-squares analysis using the rate constants of the reversible sulfonation of V as approximate initial values for those of I. The rate constant k_1 of cyclodehydration of I is related to Hammett's acidity function H_0 as expressed by the equation log k_1+H_0=-13.97. The rate of cyclodehydration of I is one-fortieth of that of 4-(p-toluidino)-3-penten-2-one (VIII) in sulfuric acid at 25°.
