低温化学是60年代末期发展起来的,十几年来显示出较大的优越性。由于制得了许多用常规化学法未能得到的新化合物,而受到化学家的重视。近几年来由于实验技术的进步。不但使合成化合物范围扩大,而且与金属有机化学和原子簇化学发生了关系,低温化学反应是在-196℃(77K)及高真空(<10~(-3)mmHg),无溶剂或有溶剂条件下进行。反应产物多为零价或低价的不稳定性化合物,具有高化应活性,可用作催化剂,化学试剂等。 Cryogenic chemistry was developed in the late 1960s, showing greater superiority over the past decade. Due to the many new compounds that have not been obtained by conventional chemical methods, chemists have paid much attention to it. In recent years due to advances in experimental technology. Not only expand the scope of the synthesized compounds, but also have relations with metalorganic chemistry and cluster chemistry. Low temperature chemical reaction is carried out at -196 ℃ (77K) and high vacuum (<10 -3 mmHg), solvent-free or solvent- Under the conditions. Most of the reaction products are low price or cheap unstable compounds, with high activity, can be used as a catalyst, chemical reagents.
