  摘要：

  The synthesis of a number of novel dibenzene-1,2-diol Mannich bases can be achieved in good yields by the condensation of 2-methoxyphenol, formaldehyde and secondary diamines. The newly developed synthetic method utilizes 2-methoxyphenol instead of benzene-1,2-diol providing a useful tool for greater control over reaction products.

  A complexing ligand for forming a complex with a cation, the ligand comprising an aromatic component including two or more attachment sites for the cation, an optionally substituted amine, such as an aminoalkylene group, and a hydrocarbon chain of from 1 to 12 carbon atoms in length. The amine component of the ligand is capable of taking on an internal counterion (H+) so that the complex of the target cation and ligand has an overall neutral charge. Such ligands can be used to extract a target cation or cations from an aqueous solution. This has particular application for the separation of aluminium and silicon in aqueous liqors in a Bayer process. The ligand can be a simple compound formed by the Mannich condensation of catechol with formaldehyde and an amine. The ligand may alternatively be a bis-ligand, a polymer or an ion exchange resin. A range of new compounds and intermediates are also described.

  一种用于与阳离子形成络合物的络合配体，该配体包括一个包括两个或多个阳离子附着位点的芳香族组分、一个任选取代的胺，如氨基烷基，以及一个长度为 1 至 12 个碳原子的烃链。配体中的胺成分能够吸收内部反离子（H+），从而使目标阳离子和配体的复合物具有整体中性电荷。这种配体可用于从水溶液中萃取目标阳离子。这种方法特别适用于拜耳法分离水溶液中的铝和硅。配体可以是儿茶酚与甲醛和胺的曼尼希缩合反应形成的简单化合物。配体也可以是双配体、聚合物或离子交换树脂。此外，还介绍了一系列新化合物和中间体。
