Ethylacrylate에 대한 n-butylmercaptan의 첨가반응속도상수를 iodometry로 측정하여 넓은 pH범위에서 잘 맞는 속도식을 구하였다. 이 식에 의하면 pH 4 이하에서는 n-butylmercaptan분자가 첨가하여 pH 7 이상에서는 n-butylmercaptide ion이 첨가함을 알 수 있고 pH 4∼7 사이에서 일어나는 복잡한 첨가반응 메카니즘도 이 식으로 잘 설명 될 수 있음을 알았다.

The rate constants for the addition reaction of n-butylmercaptan to ethylacrylate have been measured by iodometry and for the proposed reaction mechanism a rate equation which can be applied over wide pH range was derived. From this rate equation, one may conclude that the reaction is started by addition of n-butylmercaptan molecule below pH 4. However, above pH 7, this addition reaction is proceeded by the n-butylmercaptide ions. At pH 4-7, the complex addition reaction mechanism can also be revealed by this rate equation.
