一步法合成辛腈的改进

An Improved One step Synthesis of Octanenitrile

辛酸和尿素在ＦｅＣｌ３·６Ｈ２Ｏ和Ｈ３ＢＯ３催化下，一步合成辛腈。ＦｅＣｌ３·６Ｈ２Ｏ和Ｈ３ＢＯ３用量均为２％（以辛酸的质量计），辛腈的收率为８１．２％，纯度＞９７％，对其结构进行了分析确定；并讨论了影响辛腈收率的其他几个因素。

Octanenitrile was prepared by one step synthesis from octanoic acid and urea with FeCl 3·6H 2O and H 3BO 3 as catalysts,characterized by refraction index and IR.Both of the utilizable amount of catalysts are 2%(based on weight of octanoic acid),the yield of octanenitrile is 81.2%,the purity of the product is over 97%,and other factors affecting the yield are discussed.
