D315, D311, D301和D335四种大孔弱碱型丙烯酸系阴离子交换树脂被用来吸附丙烯腈和二甲基亚砜中的Fe3＋, 以纯化丙烯腈和二甲基亚砜. 通过改变温度、用量比和时间等实验条件以寻找最优的纯化条件, 实验结果证明D315大孔弱碱型丙烯酸系阴离子交换树脂的吸附效果是最佳的, 能够在室温下达到高效率低成本地纯化丙烯腈和二甲基亚砜中的Fe3＋.

关键词: 丙烯腈, 二甲基亚砜, 离子交换树脂, 纯化

Four different kinds of acrylic macroporous weak base anion exchange resin, D315, D311, D301, and D335, were employed to absorb the iron ion in acrylonitrile and dimethyl sulfoxide in order to purify acrylonitrile and dimethyl sulfoxide. The optimal purification conditions were obtained by comparing the purification result under different temperature, feeding ratio and time. It was found that the best purification result was achieved by using D315 macroporous weak base acrylic anion exchange resin and this kind of resin can purify acrylonitrile and dimethyl sulfoxide with high efficiency and low cost at room temperature.

Key words: acrylonitrile, dimethyl sulfoxide, ion exchange resin, purification
