              ether, bis(2-cyanoethyl)
              3,3'-oxybis-propanenitril

              性質描述: 無色或淺黃色油狀液體。沸點167-174℃,137-138℃(0.267kPa),相對密度1.043,折光率1.4400。溶于乙醇、丙酮、氯仿,不溶于水、四氯化碳。

              生產方法: 將季銨鹽沉積于聚苯乙烯上的強堿性樹脂加入水中,加熱至45℃,慢慢滴加丙烯腈于液面下,加畢,在45-47℃反應4-5h。反應物常壓蒸除過量的丙烯腈,然后減壓蒸餾,收集119-120℃(0.13kPa)餾分,得產品2-氰乙基醚。產率77%。

              用途: 用于有機合成。
