Direct valorization of ethane, a substantial component of shale gas deposits, at mild conditions remains a significant challenge, both from an industrial and an academic point of view. Herein, we report iodine as an efficient and selective catalyst for the functionalization of ethane in oleum at low temperatures and pressures. A thorough study of relevant reaction parameters revealed iodine to be remarkably
从工业和学术角度来看,在温和条件下直接对作为页岩气矿床重要组成部分的乙烷进行估值仍然是一项重大挑战。在此,我们报道了碘作为一种高效且选择性的催化剂,用于在低温和低压下将发烟硫酸中的乙烷官能化。对相关反应参数的彻底研究表明,在优化条件下,碘的活性明显高于先前报道的“Periana/Catalytica”催化剂。由于完全不同的催化循环,碘生成乙二醇的双硫酸氢酯 (HO3SO-CH2-CH2-OSO3H, EBS),而对于最先进的铂基催化剂,乙磺酸 (HO3S- CH2-CH2-OSO3H,ETA)作为主要产物获得。
