Diallylamine synthesis

9synthesis methods
Diallylamine is synthesized by hydrolysis of diallyl cyanamide. The hydrolysis reaction was carried out in a sulfuric acid medium, and the reflux was moderated for 6h. Yield 80-88%.
-

Yield:-

Reaction Conditions:

with sulfuric acid in water at 30;

Steps:

1.1.3; 1.1.4

(3) Dehydration section: The upper distillation component is collected and pumped into the dehydration kettle to cool down to below 30 °C, the stirring is started, and the quantitative solid alkali dehydration is added.Dehydrated oil phase water ≤ 1.5%, concentrated dehydration components to be rectified. (4) Refinement section: pumping the dehydrated component into the rectification vessel, atmospheric distillation,The pre-collection fraction was collected and the finished diallylamine was collected when the top temperature reached 112 °C. The prepared diallylamine is a colorless transparent liquid, and the color is measured by a colorimeter with a color of 18,The content of the gas was determined by GC gas chromatography to be 99.3%, and the water was measured by Karl Fischer method, and the water content was equal to 0.20%.
