| Abstract: | Using complex solvent, （2-eyanoethyl） Amylamine was synthesized by cyanoethylation with n-butylamine and acrylonitrile as raw materials.The influences of types and amounts of solvents,the proportion of rawmaterials and the time and temperature of reaction on the experimental results were studied.The optimium reaction conditions are as follow：the complex solvent which is a mixture of toluene an disopropyl alcohol （2：1）,solvent/n-butylamine =3.0-4.0 （wt/wt）, acrylonitile/n-butylamine = 1.0（mol/mo 1）, temperature50-60℃, dropping time 50 min, heat preservation time 100 min. The average yield of （2-eyanoethyl） Amylamine is 83.6%, and the purity is more than 98.0%. |
