Two racemic forms of 2-methyltartaric acid were prepared, and their optical resolutions were performed. Four optically active isomers were obtained. 2, 3-Dimethyltartaric acid was also prepared and separated into two isomeric optically inactive forms. The isomer with the higher melting point could be resolved into two optically active isomers, but the other, with the lower melting point, could not
制备了两种外消旋形式的 2-甲基酒石酸,并对其进行了光学拆分。获得四种旋光异构体。2, 3-二甲基酒石酸也被制备并分离成两种异构的旋光形式。熔点较高的异构体可以分解为两种旋光异构体,而另一种熔点较低的异构体则不能。因此,前者属于外消旋构型,而后者属于内消旋构型。
