Activated charcoal largely enhanced the rates of the alkaline hydrolysis of methyl, ethyl, and n-propyl esters in aqueous 1.5 M NaOH solution to give the corresponding carboxylic acids in excellent yields. The acidic hydrolysis of methyl, ethyl, and n-propyl esters in aqueous 3 M H₂SO₄ solution was accelerated by the addition of activated charcoal to afford the corresponding carboxylic acids in good yields.

活性炭作为水中酯类的碱和酸水解的有效添加剂

活性炭在1.5 M NaOH水溶液中大大提高了甲酯，乙酯和正丙酯的碱性水解速度，从而以极高的收率得到了相应的羧酸。通过在活性炭中加入3 MH ₂ SO ₄水溶液，可以加速甲基，乙基和正丙基酯的酸性水解，从而以高收率得到相应的羧酸。
