Bis(2-ethylhexyl) phthalate 합성의 속도론(I)-무촉매 반응-
Kinetics of Bis(2-ethylhexyl) phthalate Synthesis(I) -Non-Catalytic Reaction-
Mono（2-ethylhexyl） phthalate를 2-ethyl hexanol에 의하여 에스테르화 하는 것에 대한 반응속도론적 연구를 산및 염기와 같은 촉매를 사용하지 않을 때 그의 반응기구를 알기 위하여 행하였다.
실험적으로 결정된 속도식은 mono（2-ethylhexyl） phthalate에 대하여 2차이고 2-ethyl hexanol에 대하여는 1차이었다. 이 방정식의 온도의존성의 플로트로부터 18 kcal/mole의 활성화에너지를 얻었다.
또한 반응기구에 대한 약간의 검토를 행하였다.

Chemical kinetic study of the esterification of mono（2-ethylhexyl） phthalate with 2-ethyl hexanol was carried out to find the reaction mechanism when catalyst, such as acid or base, was not used.
The rate equation determined experimentally was second order for mono（2-ethylhexyl） phthalate and first order for 2-ethyl hexanol. The plot of temperature dependence of reaction rate constant of this equation gave an activation energy value of 18 kcal/mole.
Some discussion of the reaction mechanism was also given.
