cuprous cyanide

ⅳ was synthesized by reaction of ⅲ and cuprous cyanide in 78% yield.

最后Ⅲ和CuCN反应合成了液晶化合物Ⅳ，得率78%。

The recovered sodium cyanide and sodium cuprous cyanide can be directly returned to the plating tank.

再生回收的氰化钠和铜氰化钠可直接在镀槽内回用。

The influences of reactant ratio, reaction temperature, reaction time on substitution reaction were studied. The better reaction conditions were obtained: molar ratio of trityl chloride and cuprous cyanide was 1:1.3, reaction temperature was at 130 ℃, reaction time was 2.5h.

并通过对原料配比、反应温度和反应时间的研究，得到了较佳的合成工艺条件：三苯基氯甲烷与氰化亚铜的最佳摩尔比为1：1.3，反应温度为130℃，反应时间为2.5小时。
