L(+)-Potassium Sodium Tartrate

性状:无色结晶或白色粉末,比重1.79,PH=6.8~8,熔点70~80℃在热空气中稍有风化,60℃开始失去结晶水,热至100℃时失去3个结晶水,215℃时变为无水盐。易溶于水,不溶于乙醇。
Properties:Colorless crystals or white crystal,specific gravity is 1.79,PH value is 6.8~8,the melting point is 70~80°C.Have minute efflorescence in the heat air,lose some water when heated to 60°C,and lose 3 water molecules at 100°C,become salt without water at 215°C. Freely insoluble in water, the solution assumes minute alkalescence.
