• 中文摘要： 本文係討論經核反應產生之跳氚與乙醇在液相中的熱原子化學反應。屬抽取反應生成之含氚氫氣的產率為45%，取代反應生成含氚乙醇會因輻射劑量增加而減少。含氣乙醛是由氚乙醇之自由基分解而成，其產率在液相中為1.8%高於固相的0.8%。氣相產物包括含氚之氫氣，甲燒，乙稀等，非氣相產物為含氚之甲醇，乙醛，乙醇等。
• 英文摘要： Reaction of recoiled tritium atoms with alcohol has been studied in the liquid phase at low tem-perature. In the presence of I, the HT yield, due to the abstraction reaction was found to be 45%. TheCHTOH yield, due to the substitution reaction decreased with the increase of radiation doses. Thetritiated aldehyde product was obtained from the decomposition of (CHTOH) radical. The yield inliquid phase, 1.8%, was higher than that in solid phase, 0.8%. The gaseous products were found to be HT,CHT, CHT, CHT and while the non-gaseous products were tritiated CHOH, CHCHO and CHOH.All tritiated compounds are analyzed by radiogas chromatography.
