制备方法与用途

简介

草酸锂是以草酸与工业级单水氢氧化锂反应制备的。控制反应终点在7～7.5之间，分离后烘干即可得到高纯度的草酸锂。值得注意的是，有报道指出以草酸与氯化锂溶液制备草酸氢锂进而转化为草酸锂的方法未见报道；此外，由于氯化锂的成本较低，这使得其成为一种更具经济性的选择。草酸锂在制药工业中具有广泛的应用，并可用于制取锂盐原料。

制备

1. 将300千克的工业级单水氢氧化锂加入到1500升纯水中，在塑料容器中溶解，搅拌至溶液澄清后得到工业级氢氧化锂溶液。称取与锂元素摩尔比为1:2的草酸（质量含量299.9%）450千克，并用450升温度为90°C的纯水在搪瓷容器中搅拌溶解，形成草酸溶液。缓慢将90千克的草酸溶液加入工业级氢氧化锂溶液中，充分反应并静置10分钟，过滤除去杂质直至溶液清亮，从而获得过滤好的氢氧化锂溶液。

2. 从步骤（1）剩余的草酸溶液中取162千克加入到反应釜中，搅拌后缓慢加入步骤（1）所得的过滤好的氢氧化锂溶液至底部有少量白色沉淀生成。停止加料并充分反应；随后采用均相合成方法，在持续搅拌的过程中将剩余的过滤好的氢氧化锂溶液和剩余草酸溶液同时缓慢加入反应釜中。温度控制在约50°C，直至所有材料混合均匀后，通过添加氢氧化锂或草酸调节pH值至7.0，并继续搅拌10分钟。

3. 将步骤（2）所得的草酸锂溶液以每小时5°C的速度冷却到常温，静置待白色沉淀草酸锂全部沉入底部。收集上层清液作为溶剂返回步骤（1），并循环利用于下次反应中。

4. 采用衬四氟离心机制得湿料，随后在100℃下烘干6小时得到高纯度的草酸锂成品203千克。

  摘要：

  本发明涉及一种双三氟甲基磷酸锂的制备方法，其包括以下步骤：1）三氟碘甲烷与丙基氯化镁格氏试剂在有机溶剂中反应生成三氟甲基氯化镁；2）三氟甲基氯化镁再与二氯磷酸乙酯在有机溶剂中反应得到双三氟甲基磷酸乙酯；3）双三氟甲基磷酸乙酯与水混合发生水解反应，反应结束后，蒸馏分离，获得双三氟甲基磷酸；4）在有机溶剂存在下双三氟甲基磷磷酸与锂源反应，生成双三氟甲基磷酸锂。该方法采用三氟碘甲烷、丙基氯化镁格氏试剂、氯磷酸乙酯和锂源为原料，反应过程简单，副反应少，有利于整个过程中更有效的获得纯度高、杂质少的双三氟甲基磷酸锂，从而为获得高品质的双三氟甲基磷酸锂产品创造良好条件。
