A new liquid reagent is disclosed is form of an ionic liquid containing phosphorous acid and a tertiary amine. The reagent can be used as a replacement of phosphorous acid, where the new reagent as a liquid reagent can be handled using usual equipment for handling liquids and the dosing of the reagent can therefore be controlled more precisely in industrial plants compared to phosphorous acid, which is a solid at ambient temperature.
The new liquid reagent is particular suitable for the synthesis of bisphosphonates.
本发明公开了一种新型液体试剂,它是一种含有
磷酸和叔胺的
离子液体。该试剂可用作
磷酸的替代品,其中新试剂作为一种液体试剂,可使用处理液体的常规设备进行处理,因此,与在环境温度下为固体的
磷酸相比,该试剂的剂量可在工业设备中得到更精确的控制。
这种新型液体试剂尤其适用于合成
双膦酸盐。
