n.乙炔化合物

Cuprous acetylide takes the form of a russet or reddish-brown powder, insoluble in water and in the majority of organic solvents. 乙炔亚铜是黄褐色的红棕色的粉末，不溶于水和大多数有机溶剂。

Synthesis of carbyne by oxidation polycondensation of dicopper acetylide with Cu~(1+) and Cu~(2+) coordination as catalysis was studied by FTIR, DSC and SEM. 用FTIR、DSC及SEM对Cu+和Cu2+的催化氧化乙炔化物缩聚合成线型碳进行了研究,结果表明:Cu2+发挥了关键的作用;

Based on the experiment, we optimized the conditions of prepare linear carbon by two-steps method of oxidative coupling of copper acetylide, it spend only several hours to get the product, and the quantity of product is stable. 通过大量的实验，我们对炔烃氧化缩聚两步法合成线型碳的条件做了不小的改进，制备过程只需几小时，大大缩短了合成周期，在定量方面，使得合成条件更加明确，合成的产品质量也十分稳定;
