In order to compare the rate of hydrolysis of the same aminoalkylesters of aromatic carboxylic acids with those of aliphatic carboxylic acids, 2-diethylaminoethyl esters of cyclohexanecarboxylic acid (I), cyclohexylacetic acid (II), phenylcyclohexylacetic acid (III), propionic acid (IV), capronic acid (V), and lauric acid (VI) were synthesized and the rate of their hydrolysis in an aqueous buffer solution was measured. The aliphatic esters such as I and II were generally unstable and the stable pH ranges were found to be on the alkaline side when compared with aromatic esters of the same type. It was found that the number of methylene in the straight chain of aliphatic esters such as IV, V and VI had almost no effect on the rate of hydrolysis.
