摘要
以氧化鐵及碳酸鈣之混合物為觸媒，於溫度500°C及水蒸氣存在下，轉化乙醇為丙酮，結果大致與前人所作相若。觸媒組成之研究，較為詳細，發現觸媒之組成以氧化鐵(Fe_2O_3)與碳酸鈣(CaCO_3)之比在1：1至1：2之間，最為有利。最高轉化率為80.4%。餾餘物中之乙醇極少，不易回收，故產率亦為80%左右。副產氣體量，每耗用原料純乙醇16公克，約為三十公升，其組成為：CO_2，16-21%；H_2，70-75%；O_2，0.2-0.6%；CO，0.8-2.0%；不活性氣，3-6%。此法在適當環境下，或有工業利用之價值。

Acetone can be produced from ethyl alcohol, using iron oxide and calcium carbonate mixture as catalyst, in presence of water vapor at temperature 500°C. Attempt was made to study the effects of catalyst composition upon the conversion and yield. The most favorable result appeared a t the ratio of iron oxide to calcium carbonate from 1:1 to 1:2. The highest conversion was 80.4% and catalyst life was long. Thirty liters of gaseous by-product, containing CO_2 16-21%, H_2 70-75%, O_2 0.2-0.6%, CO 0.8-2.0%, and inert 3-6%, was formed for 16 grams of ethyl alcohol. The possibility of its commercial application is also discussed.
