Preventing Solid Distillate Accumulation during Steam Distillation When a solid is steam distilled, as in the bromination of the various aromatics we use for unknowns in the organic chemistry laboratory at Alfred University, accumulation of solid distillate in the condenser can he prevented without interruption of the distillation by installing a "pusher" in the system.
