The ρ-value of −1.8 for the oxidation of para-substituted 1-phenylethanols by sodium hypochlorite in acetic acid suggests that ketone is formed directly from alcohol by loss of a hydride. The kinetic isotope effect is 3.0. When the disappearance of oxidant is followed by iodometric titration, 5-nonanol is oxidized about 20 times faster than 1-butylpentyl hypochlorite decomposes. However, when NaCl
次氯酸钠在乙酸中氧化对位取代的1-苯基乙醇所产生的-1.8的ρ值表明,酮是由醇通过氢化物的损失直接形成的。动力学同位素效应为3.0。当用碘滴定法测定氧化剂的消失后,5-壬醇的氧化速度是次氯酸1-丁基戊基酯分解速度的20倍左右。然而,当将NaCl添加到次氯酸烷基酯中时,反应速率大致相同。
