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. 乙炔亞銅是黃褐色的紅棕色的粉末，不溶于水和大多數(shù)有機溶劑。

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對Cu+和Cu2+的催化氧化乙炔化物縮聚合成線型碳進(jìn)行了研究,結(jié)果表明:Cu2+發(fā)揮了關(guān)鍵的作用;

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. 通過大量的實驗，我們對炔烴氧化縮聚兩步法合成線型碳的條件做了不小的改進(jìn)，制備過程只需幾小時，大大縮短了合成周期，在定量方面，使得合成條件更加明確，合成的產(chǎn)品質(zhì)量也十分穩(wěn)定;
