Anionic exchang resin was chosen to adsorb hydrogen cyande from acrylonitrile.The adsorption capacity of resin was 37.08 mg/g.The adsorpion rate was above 99 % and desorpion rate was 100 %.By adding refining process of anionic exchang resin,hydrogen cyande in acrylonitrile was controling in 1 mg/g and product of acrylamide is improved.%采用阴离子交换树脂去除生产丙烯酰胺的主要原料丙烯腈中的氢氰酸,该树脂的吸附量为37.08 mg/g,氢氰酸的吸附率达99%以上,脱附率可达100%。在丙烯酰胺生产工艺中,增加离子交换树脂吸附氢氰酸精制工艺部分,可使主要原料丙烯腈氢氰酸的含量控制在1 mg/g以下,可以降低原料丙烯腈中氢氰酸对生产丙烯酰胺产品质量的影响。
