含PMP杂环的新型螯合树脂的合成

Syntheses of New Chlating Resin Containing PMP Heterocyle

以聚苯乙烯-二乙烯苯树脂小球为原料,经硝化、还原、重氮化和偶联反应合成了五种含PMP杂环的新型螯合树脂,通过元素分析、红外吸收光谱等确定了它们的化学结构,同时对新树脂螯-1、螯-3对铀(Ⅵ)离子的吸附能力进行了初步试验,结果令人满意.

In this paper, five new Chelating resin containig PMP heterocycle were syn-thesised by taking polystyrene dvinylbenzene (cross-linking degree 7%)white beads as material and through the process of nitrification, reduction, diazotization and coupling reactionl. The chemical structure of new resin were confirmed by elemental analysis and IR spectra. The adsorptive power to U(Ⅵ) of the new resin chelate-1, chelate-3 were tested preliminary. The result is satisfactory.
