Abstract: The rate of alkaline solvolysis of some diaryl esters of arylamides of phosphoric acid was measured in the mixtures water-methanol and water-2-propanol. The second-order rate constant k°_OH of hydrolytic and k°_MeO of methanolic reactions were calculated from measured rate constants k_exp , known concentration ratio of reaction products, and known ratio of lyate ions activities. The effect of methyl group in position 2 or 4 on the change of rate constants is discussed.
