Purification Methods

Crystallise it from pentane to constant melting point of -40o. A mixture of meso and d,l forms is separated by gas chromatography on an 8m stainless steel column (8mm i.d.) with 20% DEGS (diethyleneglycolsilyl chloride) on Chromosorb W (60-80 mesh) at 60o and 80mL He/min. Distil it under vacuum. [Su & Ache J Phys Chem 80 659 1976.]
