Use | for organic synthesis. |
production method | is obtained by reacting 1, 6-dibromohexane with sodium cyanide. The baked sodium cyanide powder and anhydrous dimethyl sulfoxide were mixed with stirring and heated to 60 °c. After the dropwise addition is completed, the temperature is raised to 90 ° C., stirring is continued for about half an hour, the mixture is cooled to 30 ° C. After adding chloroform, the mixture is poured into saturated sodium chloride solution, and water is added until the inorganic salt is completely dissolved, the organic phase was separated and the aqueous phase was extracted once with chloroform. The extracts and organic phases were combined and washed twice with saturated sodium chloride solution. After drying over anhydrous magnesium sulfate, chloroform was recovered first, and then distilled under reduced pressure to collect a 184-186 ° C. (2.0kPa) fraction, I .e., octinonitrile. |
