Abstract
공기 또는 산소를 산화제로 하여 Cumene을 액상산화시킬 때 유기금속촉매의 첨가에 따른 반응을 연구하였다. 본 실험에 사용된 촉매는 manganese naphthenate, cobalt naphthenate, molybdenyl naphthenate, copper phthalocyanine이었는데, 그중 cobal-naphthenate가 가장 효과적이어서, 연쇄개시 시간을 단축시키고 또한 Cumene hydroperoxide의 생성을 촉진시켰다. 그러나 무촉매산화반응과 비교하여 볼 때는 반응초기부터 dimethyl phenyl carbinol의 생성을 촉진시키는 경향이 있다.
최적 cobalt naphthenate촉매투입량은 약 5×10-8 mole/liter 이었으며, Cumene hydroperoxide의 농도는 45 %에 이르렀다.

The oxidation of cumene in a liquid-phase by contacting it with oxygen or air through a porous filter plate was studied with and without an addition of a catalyst.
Various catalysts such as manganese naphthenate, cobalt naphthenate, molybdenyl naphthenate and copper phthalocyanine were used. Of the catalysts tested, cobalt naphthenate was found to be effective in shortening the induction period and accelerating the formation of cumene hydroperoxide and simultaneously decomposing the product into dimethyl phenyl carbinol from the very early stage of reaction, which was not the case when the catalyst had not been added. The most effective concentration of cobalt naphthenate was about 5×10-8 moles per liter of cumene and the maximum concentration of cumene hydroperoxide obtained was about 45 %.
