本研究主要藉由程序控溫反應/脫附(Temperature-programmed reaction/desorption，TPR/D)、反射式吸收紅外光譜(Reflection-absorption infrared spectroscopy，RAIRS)及歐傑電子光譜(Auger electron spectroscopy，AES)探討在超高真空系統中，2-丁炔酸(CH3C≡CCOOH)於Cu(100)和O/Cu(100)表面上的吸附及熱反應。
CH3C≡CCOOH的熱分解造成H2O(215 K)，H2(340 K, 510 K)，CO(340 K)，CO2 (340 K)及CH3C≡CH(340 K, 490 K)的脫附。RAIRS顯示275 K有CH3C≡CCOO(a)的生成。另外215 K的H2O可能來自OH(a)的生成，因此不排除有產生CH3C≡CCO中間物的可能性。0.5 L CH3C≡CCOOH/O/Cu(100)系統中，CH3C≡CCOOH的分解造成H2O(180 K, 280 K, 370 K)，H2 (280 K)，CO(280 K)，CO2 (280 K)。110 K已有CH3C≡CCOO(a)生成。表面氧原子會與CH3C≡CCOO(a)反應，可能涉及CH3，導致CH3C≡CCOO(a)在Cu(100)上的熱穩定度降低。

The adsorption and thermal reactions of 2-butynoic acid on Cu(100) and oxygen-precovered Cu(100) have been studied in ultra-high vacuum system by using the surface techniques of temperature-programmed reaction/desorption (TPR/D), reflection-absorption infrared spectroscopy (RAIRS) and Auger electron spectroscopy (AES).
Thermal decomposition of 0.5 L CH3C≡CCOOH on Cu(100) causes the desorption of H2O(215 K), H2(340 K, 510 K), CO(340 K), CO2 (340 K) and CH3C≡CH(340 K, 490 K). RAIRS shows the formation CH3C≡CCOO(a) at 275 K. The possibility for the formation of reaction intermediate, CH3C≡CCO(a), due to the H2O desorption at 215 K, possible from OH(a), cannot be ruled out. In the case of 0.5 L CH3C≡CCOOH/O/Cu(100), the reaction products are H2O(180 K, 280 K, 370 K), H2 (280 K), CO(280 K), CO2 (280 K). There is evidence for the CH3C≡CCOO(a) generation at 110 K. Reaction of CH3C≡CCOO(a) with pre-adsorbed O (possibly involving CH3) decrease its thermal stability on Cu(100).
