A possibly better method of separating the isomeric mononitrotoluenes is. one used by the firm of Meister, Lucius Bruning. This consists in cooling the mixed nitrotoluenes to —4 to —10 °, and removing the liquid portion after about one-half the mixture has ci ystallized. The separation may be effected by a centrifuge. The liquid obtained by one crystallization is practically pure ortho nitrotoluene. The resulting mixture of meta and para nitrotoluenes may be separated by steam distillation. The para is very volatile with steam, while the meta is but slightly so.
