3,3-二丙腈硝胺的合成

Synthesis of 3,3Bispropanenitrile Nitroimino

以丙烯腈和氨水反应合成了３，３二丙腈胺，仲胺得率为７０．７％；将其在硝酸、乙酸酐和浓盐酸体系中硝化得３，３二丙腈硝胺。当反应物仲胺与硝酸、乙酸酐和浓盐酸物质的量比为１∶２∶２∶０．０９时，在３５℃反应１．５ｈ，硝化产物得率为９３．４％。

Based on concentrated ammonium hydroxide and acrylonitrile,3,3bispropanenitrile amine is synthesized and nitrated to 3,3bispropanenitrile nitroimino in nitric acid,acetic anhydride and hydrochloric acid.When at a molar ratio of secondary amine to nitric acid to acetic anhydride to hydrochloric acid is 1220.09 and at 35 for 1.5h,the yield of nitration product is 93.4%.
