Purification of duplex dicarboxyl-base lithium borate

Purification of bioxalate-lithium borate is carried out by packing the crude product LiB(C2O4)2 by filter cloth, putting it with solvent into reactive kettle, sealing, heating, gasifying the solvent in kettle, pressurizing at 200Kpaí½800Kpa in proportion of LiB(C2O4)2:solvent=1:2í½1:5, reacting, low...

Zusammenfassung:Purification of bioxalate-lithium borate is carried out by packing the crude product LiB(C2O4)2 by filter cloth, putting it with solvent into reactive kettle, sealing, heating, gasifying the solvent in kettle, pressurizing at 200Kpaí½800Kpa in proportion of LiB(C2O4)2:solvent=1:2í½1:5, reacting, lowering temperature, taking out filter cloth, crystallization precipitating out LiB(C2O4)2, separating LiB(C2O4)2 from solution and drying to obtain final product. It is simple and cheap, has more yield and high purity. It can be used for industrial production.
