Production method | is obtained by the reaction of dibromopropane and sodium cyanide. Dissolve sodium cyanide in water, add ethanol of dibromopropane, cool, and filter out the precipitation. Take the mother liquor with ethyl acetate and wash the extract with water. After being dried by potassium carbonate, ethyl acetate is recovered, and the residue is distilled under reduced pressure. The fraction at 144-147 ℃(1.73kPa) is collected as the finished product, with a yield of about 80%. |
