摘　　要：以十二醇和丙烯腈为原料在碱性条件下生成3-正十二烷氧基丙腈,然后在雷尼镍催化作用下加氢合成3-正十二烷氧基丙胺,反应总收率为90.09%(以正十二醇计)。将该捕收剂应用于鞍山式铁矿石的反浮选试验,与现场阴离子捕收剂相比,在精矿品位相近的情况下,尾矿降低3.24%以上、浮选作业回收率提高3.13%左右。Under basic conditions, 3-nC12H25OCH2CH2CN was made from dodecanol and acrylonitrile. After then, it was hydrogenated to synthesize 3-nC12H25OCH/CH2CH2NHz with Raney-Ni as catalyst. The total yield was 90.09% （counted by dodeeanol） . The cationic collector was used in the reverse flotation test of Anshan iron ores. Compared with the anionic collector on site, it can decrease tailings by 3.24% and improve the recovery by 3.13% under the condition of similar Fe concentrate grade.
