1,1-Dicyano-2-p-dimethylaminophenyl-2-chloroethylene의 가수분해 반응메카니즘과 그의 반응속도론적 연구
The rate constants of hydrolysis of 1,1-dicyano-2-p-dimethylaminophenyl-2-chloroethylene(DPC) were determined at various pH and the rate equation which can be applied over wide pH range is obtained. From the rate equation the mechanism of the hydrolysis of a DPC over wide pH range is fully explained...

| description | The rate constants of hydrolysis of 1,1-dicyano-2-p-dimethylaminophenyl-2-chloroethylene(DPC) were determined at various pH and the rate equation which can be applied over wide pH range is obtained. From the rate equation the mechanism of the hydrolysis of a DPC over wide pH range is fully explained; below pH 3 and above pH 7.5, the rate constant is proportional to the concentration of hydronium ion and hydroxide ion, respectively. However, in the range of pH 3 to 7.5, water, hydronium ion and hydroxide ion catalyze the hydrolysis of DPC. 여러 pH에서 1,1-dicyano-2-p-dimethylaminophenyl-2-chloroethylene(DPC)의 가수분해 속도상수를 측정하고 넓은 pH 범위에서 잘 맞는 반응 속도로식을 구하였다. 이 식에 의하면 넓은 pH 범위에서 DPC에 대한 가수분해 반응메카니즘을 잘 설명할 수 있다. pH3이하와 7.5이상에서는 속도상수는 hydronium ion과 hydroxide ion 농도에 각각 비례한다. 또 pH 3∼7.5 사이에서는 물, hydronium ion 과 hydroxide ion이 DPC의 가수 분해에 촉매 역활을 함을 알았다. |
