A clock reaction produced by mixing chlorate and iodine solutions in perchloric acid media is reported. This is the first example of a clock reaction using chlorate as a reagent. Increasing chlorate and acid concentration reduces the induction period. Changing the initial iodine concentration does not affect the length of the induction period. The discovery of this clock reaction opens the possibility that a new family of oscillation reactions can be built using chlorate as reagent.
据报道，在高氯酸介质中混合氯酸盐和碘溶液会产生一种时钟反应。这是使用氯酸盐作为试剂的时钟反应的首个实例。增加氯酸盐和酸的浓度会缩短诱导期。改变初始碘浓度不会影响诱导期的时长。这种时钟反应的发现开启了利用氯酸盐作为试剂构建新的振荡反应家族的可能性。
