• 中文摘要： 迄今鈾化學的基本研究結果指出大部份鈾碳鍵為不穩定，然而我們先前報導過的工作，鈾粉為催化劑下能使炔類、共軛二烯或鹵化丙烯等物質聚合。本工作就是探討合成石油的可能性，先驅工作為證明非非兀一物質亦能經過鈾粉使碳碳接合，易於分裂成自由基的二碘甲烷重氮甲烷等，在鈾粉存在下常溫即能使碳的數目增至C ，同時實驗中發現有趣的現象，碳的數目隨反應時間的增長而增加一氧化碳與氫氣在鈾粉存在下壓力約為1大氣壓溫度250℃的反應條件，產生甲烷 (60-70%)甲醇（20-25％）乙醇、二甲醇基甲烷等。同時利用鈾化烷基化合物熱解所產生氣體化合物，來支持上述合成石油過程可能的中間產物鈾化烷基。
• 英文摘要： In the study of the catalytic reaction of uranium powder, phenylactylene and dimethylacetylened-icarboxylate were converted to polymers via linear-oligomerization and cyclo-oligomerization reactions.Our results indicate a new synthetic pathway of the carbon-carbon bond formation through the partipipa-tion f-orbital elements. In this report, reactions of methylenediiodide, diazomethane and ketene werestudied. The products of these reactions, i.e., C and C alkanes and alkenes, suggested that the bondcould be formed by the insertion of methylene radicals. An interesting phenomenon, where the carbonnumber of products increased with the duration of reaction period, was found. The role of the uranium element in the Fischer-Tropsch process was studied. Hydrogen and carbonmonoxide were catalyzed to methane（60-70％）， (方程式無法摘錄) （20-25％）, (方程式無法摘錄) and (方程式無法摘錄) at oneatmosphere pressure, 250℃. The Fischer-Tropsch process could proceed through uranlum aikoxide inter-mediates. This oxide-formation mechanism was tested by the pyrolysis of uranium alkoxides.
