          產品介紹

          有二個不對稱碳原子,有四種立體異構體,即:右旋型(D型, L型)、左旋型(L型,D型)、內消旋型、外消旋型。通常,外消旋型酒石酸又稱為葡萄酸。右旋型酒石酸以游離的或K鹽、Ca鹽、Mg鹽的形態廣泛分布于高等植物中,特別是多存在于果實和葉中。等量右旋體和左旋體的混合物的旋光性相互抵消,稱為外消旋酒石酸。內消旋體不存在于自然界中,可由化學合成。各種酒石酸都是易溶于水的無色結晶。

          熔點:172-174 ℃

          沸點:191.59℃ (rough estimate)

          比旋光度:-12.1 o (C=20, H2O)

          外觀:白色粉末或結晶

          溶解性:可溶于水

          敏感性:對光敏感

          儲存條件:2-8℃
