摘要:液-液萃取是从天然和回收资源中生产稀土元素 (Ree) 的最具规模化的工艺之一.加速稀土制造可持续工艺的研究,开发和部署 (Rd&d) 既需要大规模地轻松合成提取配体,又需要快速评估工艺条件.在这里,我们建立了一个综合的研发方法,包括灵活的配体合成和自动化高通量提取研究.以二甘醇酰胺 (Dga) 为例,我们首先开发了一种通过无溶剂熔融酰胺化反应直接偶联二甘醇酸和仲胺来合成 Dga 的方法(可扩展到 200 G). 9 种不同 Dga 的熔融酰胺化合成底物范围已得到证实,具有非常好的收率 (85-96%) 和纯度 (88-96%),无需任何反应后后处理或纯化过程.生命周期评估表明,我们的合成方法在每个环境影响类别中均优于现有技术途径,特别是显示全球变暖潜力降低了 67%.此外,我们使用自动化,高通量的液-液萃取工作流程研究了各种烷基取代的 Dga 的结构-活性关系,在 48 小时内实现了 180
